Parameters

Reflection

Refraction

1.

Definition

Reflection is considered as the bouncing back of light when it falls on a surface.

Refraction is considered as the bending of rays of light when it travels from one medium to another medium.

2.

Surface

It takes place on shiny surfaces that allow bouncing back of light without passing through it.

It takes place in the transparent surface that allows the bending of light rays to a different medium.

3.

Type

It follows two forms of reflection i.e. regular reflection and diffused reflection.

It follows a single form of refraction.

4.

Occurrence

It takes place only in mirrors.

It takes place only in lenses.

5.

Nature of light

Here, the light ray bounces back in the same direction.

Here, the light ray passes from one medium to another.

6.

Speed of Light

The speed of light does not vary.

The speed of light is changed from one medium to another.

7.

Medium of propagation

The medium of propagation of light remains the same.

The medium of propagation of light gets changed.

8.

Angles of reflection and incidence

The angle of incidence and reflection are the same.

The angle of incidence and refraction are different.
