Question
1) When a beam of light (wavelength = 590 nm), origionally traveling in air, enters a piece of glass (index of refraction 1.50), Find its wavelength in glass.
2) A ray of light, which is traveling in air, is incident on a glass plate at a 45 degree angle. The angle of refraction in the glass
a. is less than 45 degrees
b. is greater than 45 degrees
c. is equal to 45 degrees
d. could be any of the above; it depends on the index of refraction in glass
3) Red light with a wavelength of 650 nm travels from air into a liquid with an index of 1.33. What is the frequency and wavelength in the liquid?
Explanation / Answer
1)
L' = L/n = 590nm/1.5 = 393.33 nm
2) a. is less than 45 degrees
3) f = c/L = (3*10^8)/(650*10^-9) = 461.54e+12 Hz
L' = L/n =488.72 nm
