Begginers Chemistry Help......?

Question

"Choose colors of light produced for three of your samples and find an approximate wavelength that corresponds to that color. Now find the frequency and energy of each color."
--
The colors are yellow, blue, and green; how do I do this? (I remember her telling us, but I forget and dont have my book with me)

Thanks Alot

Answer 1

Boy..... you are sooooo Scr*wed

1) What you wrote is not a question... no one will have ANY idea of what you are asking

2) How are we supposed to know what samples you have such that we can determine the information outlined in the statement.

You would do better to contact someone in the class so you can understand what you are supposed to be doing.

Sorry..

Answer 2

You have to look up these facts (givens) on the internet then.

Each of these colors corresponds to light of a given wavelength range. These are measured, not calculated, values. Therefore, they are "givens".

Invert the wavelength to get the frequency.

Energy = hc/wavelength (DeBroglie's equation). You also have to look up "h" (Planck's constant), as I don't remember exactly what this constant is. But it's just another "given".

You'll be done in no time.
