उत्तर
Frequency
Explanation:
The interaction of light with the atoms at the surface of separation results in both reflection and refraction. You may think of these atoms as oscillators. Such atoms are made to vibrate at the frequency of light when light strikes them. Both the reflected and refracted lights have the same frequency as the incident light since the light output by these charged oscillators is equal to their own oscillation frequency.

A monochromatic ray of light falls on a regular prism under minimum deviation condition. What is the relation between angle of incidence and angle of emergence?
Assertion(A): The photoelectrons produced by a monochromatic light beam incident on a metal surface have a spread in their kinetic energies.
Reason(R): The energy of electrons emitted from inside the metal surface, is lost in collision with the other atoms in the metal.
