here the problem: In the Young Double Slit experiment, alternatingbands of bright and dark regions are produced on the screen. At the dark band shown in the picture below, on slit is a closer than the other slit: In other words, D1 is less than D2, Find D2-D1, Assuming that the light has a...

Here is the Question. You observe water waves coming to shoreon a large lake. You obseve that every five seconds, two more waves come in, and that the waves are seperatedby four meters. a) What is the period of the waves? b) What is the frequency of the waves? c) What is the velocity of...

wave period, say when dealing with ocean waves.

So the frequency of differnt color light doesn't effect the speed at which these colors of light travel.? Becuase 2 differnt colors of light in the same medium wil travel at the same speed..Right? One other question. What is a wave period. Is it the same as the wave length?

I am:biggrin:

Ok is there a differnce in... Ok is there a differnce in speed when dealing with blue light and yellow light in air. I have tried read the doppler effect over and over, but so All I can see pertaining to is that one color indicates an object moving away and one moving towards. Light is light...

Well not nothing. The refractive index of a medium will decrease it. Right? The speed of light in glass is slower than in a vaccum. Right??

Take light in glass. What could slow it down. I know that stuff is asorbed and then reemmited, but what about imperfections in the glass its self?? Say you have a piece glass that has impurities(little defects), or the desity of glass(not optical), the actual wave length of light, or for giggles...
