The angle between the normal and the incident ray is known as the:
Angle of incidence
Angle of reflection
Angle of refraction
Angle of normal
The angle between a ray incident on a surface and the normal at point of incidence is known as the angle of incidence.
The angle between the normal at the point of incidence and the reflected ray is known as:
The angle between the normal at the point of incidence and the incident ray is known as:
