Question

Define the following terms :
Incident ray, Refracted ray, Angle of incidence,
Angle of refraction.
​

Answer 1

Explanation:

Incident ray - A ray of light falling on the surface separating two mediums is the incident ray.

Refracted ray - A ray of light traveling in another medium, with change in direction is the refracted ray.

Angle of incidence - The angle which the incident ray makes with the normal is called angle of incidence.

Angle of refraction - The angle which the refracted ray makes with the normal is called angle of refraction.

Answer 2

Hey dear, here is your answer
Incident ray- An incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence.
Refracted ray-A ray that undergoes a change of velocity, or in the general case, both velocity and direction, as a result of interaction with the material medium in which it travels.
Angle of incidence-the angle which an incident line or ray makes with a perpendicular to the surface at the point of incidence.
Angle of refraction-the angle made by a refracted ray with a perpendicular to the refracting surface.
