Convert Frequency to Wavelength Worked Example Problem

This example problem demonstrates how to find the wavelength of light from the frequency. Frequency vs Wavelength The wavelength of light (or other waves) is the distance between subsequent crests, valleys, or other fixed points. The frequency is the number of waves that pass a given point in one second. Frequency and wavelength are related terms used to describe electromagnetic radiation or light. One simple equation is used to convert between them: frequency x wavelength speed of light ÃŽ » v c, when ÃŽ » is wavelength, v is frequency, and c is the speed of light so wavelength speed of light / frequency frequency speed of light / wavelength The higher the frequency, the shorter the wavelength. The usual unit for frequency is Hertz or Hz, which is 1 oscillation per second. Wavelength is reported in units of distance, which often ranges from nanometers to meters. Conversions between frequency and wavelength most often involve wavelength in meters because thats how most people remember the speed of light in a vacuum. Key Takeaways: Frequency to Wavelength Conversion Frequency is how many waves pass a defined point per second. Wavelength is the distance between successive peaks or valleys of a wave.Frequency multiplied by wavelength equals the speed of light. So, if you know either the frequency or the wavelength you can calculate the other value. Frequency To Wavelength Conversion Problem The Aurora Borealis is a night display in the Northern latitudes caused by ionizing radiation interacting with the Earths magnetic field and the upper atmosphere. The distinctive green color is caused by the interaction of the radiation with oxygen and has a frequency of 5.38 x 1014 Hz. What is the wavelength of this light?Solution:The speed of light, c, is equal to the product of the wavelength, lamda;, and the frequency, ÃŽ ½.ThereforeÃŽ » c/ÃŽ ½ÃŽ » 3 x 108 m/sec/(5.38 x 1014 Hz)ÃŽ » 5.576 x 10-7 m1 nm 10-9 mÃŽ » 557.6 nmAnswer:The wavelength of the green light is 5.576 x 10-7 m or 557.6 nm.

The National Assembly - 1012 Words

On August 26, 1789, the National Assembly introduced the Declaration of the Rights of the Man and of the Citizen which proclaimed, â€Å"Liberty, property, security, and the right to resist to oppression†. The National Assembly had abolished feudalism and ended serfdom. It also took over church lands to pay off the national debt that France had acquired. This action alarmed many peasants who were devout Catholics. The National Assembly established civil equality among men and made more than half of the male population able to vote. Meanwhile, fear of royal troops started to spread, and many radical groups who wanted great changes started to form. The ancien regime had officially ended, and the National Assembly attempted to create a constitutional monarchy like England. They produced many changes and reform in France, and all was well until King Louis XIV, Marie Antoinette, and their family tried to escape the country for safety. The Flight to Varennes occurred in June, 1791. The royal family was eventually recognized and brought back to Paris. King Louis was now seen as a traitor and put under guarded arrest. The French Revolution brought new hope to other revolutionaries who had been defeated before. Other countries, like England, Germany, and Italy, who wanted change were inspired by the French Revolution. The National Assembly spent two years trying to create a new constitution for France.

Business Strategy Adopted by Ebay in the Evolution free essay sample

Discuss the business strategy adopted by eBay in the evolution of its internationalization efforts? eBay is an online peer to peer auctioning platform that allows people from all over the world to sell and trade goods. eBay was setup nearly 13 years ago and has seen its net revenues grow into the billions ever since. eBay acts an intermediary between sellers and buyers to provide a safe and secure environment for people to browse, buy or sell products that are new, used or hard to find. The system works just like a real auction where bids are placed on products, with the highest bid winning when the clock stops. Bay puts both parties in touch with each other without ever touching the product and when the deal has gone through, eBay takes between 7% and 18% of the sale price. Its business strategy is based on three pronged approach which encompasses an online community to buy and sell goods. We will write a custom essay sample on Business Strategy Adopted by Ebay in the Evolution or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Included within this is the security which it offers users, this piece of mind granted to users is brought about by another core-competency of eBay, which is cutting edge technology. This technology has granted ebay the opportunity to evolve its internationalization efforts over the past number of years. At the core of eBays business strategy is the sense of community among users whilst using the service. Users from all over the world (more then 150 countries) have to be able to converse and describe their products in their native language; otherwise the feeling of a global community will become nothing more then a regionalised and segregated market place. The process of adopting computer software to different languages and cultures has been a main goal of eBay and in 2004 its progress in this field became evident when it deployed software that could translate foreign language web-pages into English in less then 30 seconds. Since then eBay has been gradually upgrading its software with new features such as a vendor management tool, better search engines and more flexibility in applying local security policies. Since eBay realised that international markets have more then twice the amount of users as American market this strategy has become more focused on global markets with the advent of its cultural technology.

The Three Parenting Styles

Introduction Parenting is a stage of life that comes about when one gets children to bring up. It is natural and there are no manuals or rules to parenting as people just learn about it as they go. Though there are many ideas on how to bring up children some will be individual based, others from their own parents while others will adopt ideas from their friends. Parenting styles can be described as the ways parents use to parent their children (Aunola et al 217).Advertising We will write a custom essay sample on The Three Parenting Styles specifically for you for only $16.05 $11/page Learn More Psychologists have therefore established three different parenting styles that are used by parents either with or without their consent. The parenting styles, permissive, authoritative and authoritarian are usually based on the communication styles, disciplinary strategies as well as warmth and nurture. This paper is therefore an in-depth analysis of the three bas ic parenting styles used by most parents. Permissive Being permissive entirely means not being strict. This style of parenting is where the parents let their children to make decisions on their own. Most of the control is left in the hands of the children themselves, though the parents come in to make a few rules if any. Nevertheless, the rules made by the parents are not meant to tie down the children and are thus not consistently enforced (Then 1). Parents using this parenting style usually want to make their children to feel free. They also tend to accept their children’s behaviour and acts regardless whether they are good or bad. This is because they tend to feel unable to make them change hence choosing not to be involved with their children’s lives. Therefore, this parenting style is characterised by a lot of affection and warmth as the children are not subject to punishment no matter what they do. The good thing about this style is the fact that communication is always open and parents are able to discuss anything with their children. This parenting style has been described to be not the best as children require proper guidance as they grow and being left to choose what they want on their own could make them make the wrong decision which could affect their entire life. However, children who are critical thinkers may grow up being good decision makers as they have been exposed to such conditions before. Authoritarian This is the opposite of the permissive style of leadership. In this style the parents set up clear-cut rules and guidelines which are deemed to be followed by the children. The parents therefore expect their children to obey them or else get punished. Nurturing is very rare in this leadership as the children are rarely left free. The parents tell their children what to do and make decisions on their behalf without explaining to them (Then 1).Advertising Looking for essay on psychology? Let's see if we can help you! Get you r first paper with 15% OFF Learn More Parents using this style tend to focus more on the negatives rather than the positives such that a child who fails in school or wrongs is severely punished or scolded while the one who has exemplary passed is rarely praised. The children who grow up under this parenting style do not learn to think and do things on their own thus find it very difficult to make decisions later in life. This parenting style is mostly applicable to children who are very stubborn and need to be closely monitored. Authoritative This parenting style is also referred to as the democratic style as parents help their children to learn about themselves, being responsible for themselves and their behavioural consequences (Iannelli 1). This style is described as the best as it is a blend between permissive and authoritarian parenting styles. Parents using this style using set the necessary rules and enforces them while taking each situation as it comes. The democrat ic parents usually want to make their children understand why they are being punished because of unacceptable behaviour or breaking up of rules. It is because of this reason that punishment is usually discussed with the children before being implemented. As a matter of fact, parents and children work hand in hand thus ensuring that the children respect their parents while the parents do not oppress their children as well. Conflicts under this parenting are handled in a reasonable manner without hurting either party. Conclusion The parenting styles discussed above are applicable depending on the views people hold for each. Each of the three parenting styles has its own merits and demerits. In the permissive parenting style the parents have adequate time to do what they would wish to do since they are not constantly monitoring the children (Spera 2). Chances of separation in such a family are very high since people develop their own different lives. In the authoritarian parenting styl es children tend to be very respectful thus parents have low levels of stress. The democratic style on the other hand is very involving for the parents as they have to be on toes and talking with their children to keep the unity of the family.
