Plane Mirrors

Front

What is a plane mirror?

Back

A flat reflective surface that reflects light according to the law of reflection.

Front

What is the law of reflection?

Back

The law states that the angle of incidence is equal to the angle of reflection.

Front

Define angle of incidence.

Back

The angle formed between the incident ray and the normal at the point of incidence.

Front

Define angle of reflection.

Back

The angle formed between the reflected ray and the normal at the point of reflection.

Front

What is the normal line in the context of reflection?

Back

An imaginary line perpendicular to the surface of the mirror at the point of incidence.

Front

How is the angle of incidence measured?

Back

It is measured from the normal to the incident ray.

Front

How is the angle of reflection measured?

Back

It is measured from the normal to the reflected ray.

Front

What happens to light when it strikes a plane mirror?

Back

It is reflected according to the law of reflection.

Front

What is the relationship between the angle of incidence and the angle of reflection?

Back

They are always equal to each other.

Front

What is meant by 'reflected ray'?

Back

The ray of light that bounces off the surface of the mirror after reflection.
