Expert Answer:

(d) None.

Since it's a plane reflecting surface, absorption or transmision of light will be zero.

Hence no change in the wavelength of the relfected light.

Hence (a) is true.

(b) is also true since it's the frequency for 5000 A wavelength.

(c) is also true since angle of reflection with the normal will be 45 and is equal to the angle of incident.

Hence the reflected ray is perpendicular to the incident ray.
