Recall Activity: Law of Reflection

Front

What is the Law of Reflection?

Back

The Law of Reflection states that the angle of incidence is equal to the angle of reflection when light reflects off a surface.

Front

Define angle of incidence.

Back

The angle of incidence is the angle formed between the incident ray and the normal (a line perpendicular to the surface) at the point of incidence.

Front

Define angle of reflection.

Back

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

Front

What happens to light when it strikes a mirror?

Back

When light strikes a mirror, it reflects off the surface according to the Law of Reflection.

Front

What is reflection in terms of light?

Back

Reflection is the bouncing of light off the surface that it strikes on.

Front

If the angle of incidence is 30 degrees, what is the angle of reflection?

Back

30 degrees.

Front

What is a source of light?

Back

A source of light is an object that emits light, such as the sun, a candle, or a lamp.

Front

Which of the following is not a source of light: candle, mirror, sun?

Back

Mirror.

Front

What is the normal line in reflection?

Back

The normal line is an imaginary line that is perpendicular to the surface at the point where the light ray strikes.

Front

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

Back

The angle of incidence is always equal to the angle of reflection.
