Chapter II Light and Matter The Inner Workings of the Cosmos 2.4 The Distribution of Radiation All microscopic objects – fires‚ cubes‚ people‚ and stars – emit radiation at all times. They radiate because the microscopic charged particles in them are in constant random motion‚ and whenever charges change their state of motion‚ electromagnetic radiation is emitted. The temperature of an object is a direct measure of the amount of microscopic motion within it. The hotter the object

Xxx.comTheories of light In the seventeenth century two rival theories of the nature of light were proposed‚ the wave theory and the corpuscular theory. The Dutch astronomer Huygens (1629-1695) proposed a wave theory of light. He believed that light was a longitudinal wave‚ and that this wave was propagated through a material called the ’aether’. Since light can pass through a vacuum and travels very fast Huygens had to propose some rather strange properties for the aether: for example; it must

Purpose: To investigate the behavior of light when it passes from air into an optically denser medium. Prediction / Hypothesis: When the light (incident ray) passes from air into an optically denser medium with an angle of incidence equal to zero‚ there would be no refraction. When the light passes at an angle from air into an optically denser medium‚ the light (incident ray) will immediately change direction and bent towards the normal which has an angle of incidence of 0. Method:

Conclusion: Explain‚ in your own words‚ why different elements produce different colors of light when heated. Each element has a unique electron configuration. When heated‚ the electrons are energized and this leads to a higher quantum state. The color depends on the distance you have and the original electron configuration. Why do you think elements must be heated before they emit colored light?The light color is the electronic transitions between orbitals. When an electron drops to a

Traffic Light If I were to court a boy‚ I would be like the traffic light. I am color yellow‚ whispering take everything slowly but surely. I am color green‚ saying go when everything is going strong. I am color red‚ shouting stop when everything goes wrong. I see color yellow. I let myself stay firm to wait. I just keep waiting for my turn. I am in the middle. I stay neutral. I shall not go fast‚ but shall fire up and set. If I remain sluggish and dawdling‚ I will be left out. If I go too

If a song‚ film‚ poem‚ novel‚ play or painting possesses the ability to touch audiences of any era or culture‚ then it is truly successful. Notable movements of artwork are associated with the time in which they were produced

Light Sura The Sura I have chosen to analyse for my assignment is the ‘Light Sura’. The reason I chose this Sura is that it deals with many social issues that are still very evident in Islamic life today. It gives a very detailed view of what God expected of its followers throughout the Sura and what punishment would be handed to them if they did something unwilling to Gods orders. Throughout the Sura a strong message is sent to the believers of Islam. A woman is used as an example of someone
