The energy that light carries is related to the frequency of the light by the equation
E = hf
where h is a constant equal to 6.626x10 -34 Js. Blue light of wavelength 400 nm passes from air into a medium with an index of refraction of 1.7.
(a) What is the energy of the light in air?
(b) What is the energy of the light in the medium?
