Question

light of wavelength
5000 A falts on a
plane reflecting surface what are the
wave length
and 'Frequency of the
refracted light? For what angle of
incidence is the
reflected ray normal
to the incident
ray ?
​

Answer 1

Answer:

What are the wavelength and frequency of the reflected light? For what angle of incidence is the reflected ray normal to the incident ray? The wavelength and frequency of incident light is the same as that of reflected ray. Hence, the wavelength of reflected light is 5000 Å and its frequency is 6 × 10 14 Hz.
