The frequency of a light wave is the same when the light travels in ethyl alcohol as it is when it travels in benzene. What is the ratio of the wavelength of the light in ethyl alcohol to that in benzene?
wavelength ethyl alcohol / wavelength benzene
also, i know that the index of refraction of Ethyl alcohol is 1.362
and the index of refraction of Benzene is 1.501
not sure if those calculations are relevant for the wavelengths of these liquids or not.
This doesn't seem to be a hard ratio to calculate, but i know i'm not find the index of refraction for a material or the speed of light. Need help finding the wavelength ratio.
