If the wavelength of red light in air is 816 nm, What is it's frequency? If I use the equation F=c/wavelegth -> with c being 3 x 10^8m/s, why can't I get the right answer? I even converted the 816 nm to 8.16 x 10 ^ 11 m. :confused:

description if diagram Ok, so there is a beam coming down hitting the surface of the water and 29.9 degrees to the horizontal. (that's the theta i) The beam comes down into the water where it moves away from the normal because n2>n1. The angle of refraction that I found was 21.95(that's theta...

Given any index of refraction, how would I find a wavelength in that medium? Should I use frequency= c/wavelength? For example, if a piece of glass (medium) has a index of refraction 1.12, what's the wavelength?

I am having A LOT of trouble figuring this one out. . .Some please help.. ok here it goes- So there is a beam of light (with and angle of incidence of 29.9 degrees) and so using snell's law I calculated that the angle of refraction is 21.95 degrees (using n1 as air and n2 as water). The ray...
