Question

Light of wavelength 5000a° falls on a plane relecting surface. What are the wavelength and frequency of the reflected light. For what angle of incidence is the reflected ray normal to the incident ray

Answer 1

Answer:

The wavelength and frequency of incident light is the same as that of reflected ray. Hence, the wavelength of reflected light is 5000Å and its frequency is 6 x 1014 Hz. Therefore, the angle of incidence for the given condition is 45°.
