Question

(a) Calculate the wavelength of light in vacuum that has a frequency of 3.4 107 Hz.
________m

(b) What is its wavelength in benzene? (The index of refraction of benzene is 1.501.)
_________m

(c) Calculate the energy of one photon of such light in vacuum. Express the answer in electron volts.
_________eV

(d) What is the properties of and effect on the energy of the photon when it enters the benzene? (Select all that apply.)
1)the energy is proportional to the frequency
2)the energy does not change
3)the energy goes up
4)the energy is not proportional to the frequency
5)the energy goes down
6)the energy is inversely proportional to the frequency

Explanation / Answer

a) = c/f = 8.823 m
