The perpendicular line drawn on the surface of a mirror at the point of incidence is called the incident ray.

The perpendicular drawn at the point of incidence is called ____.

A ray which bounces off the surface of a mirror is called incident ray.

For a fixed incident light ray, if the mirror be rotated through and angle theta (about an axis which lies in the plane of mirror and perpendicular to the plane of incidence), show that the reflected ray turns through an angle 2 theta in same sense.

The diagram in Fig shows an incident ray AO and the reflected ray OB from a plane mirror. The angle AOB is 30^@ . Draw normal on the plane mirror at the point O and find : (a) the angle of incidence (b) the angle of reflection

Ligtht falls on a plane reflecting surface.For what angler of incidence is the reflected ray normal to the incident ray.

When a ray of light strikes a plane mirror along the normal, the angle of incidence is :

A light ray is incident normally on a plane mirror. What is the angle of incidence?

The perpendicular distance between the incident ray and the emergent ray in a glass slab is called the ..................... (angle of emergence/lateral displacement).

A ray of light falls normally on a plane mirror. What is the angle of incidence ?

When a ray of light falls normally on a plane mirror. The angle of incidence will be
