Solution

The correct option is B If both assertion and reason are true and reason is not the correct explanation of assertion.
The frequency of the incident, reflected and refracted beam depends on the source of the light because it is the property related to the energy of the light. It does not vary with the change in the medium.

The incident, reflected and refracted ray all lie in the same plane and therefore they are coplanar.

The assertion and reason both are correct but the reason is not the correct explanation of assertion.
