Question

What physical quantity can be found in an experiment done with prism

Answer 1

COLOUR  CAN BE FOUND.

Answer 2

We use glass prism to demonstrate the refraction of light.

Refraction is the bending of light when light travels from one medium to another.

In the case of a prism the light is travelling from air through the prism.

Refraction happens due to the difference in densities of different mediums.

In this case a glass prism is more dense than air.

In this case the light will be refracted as it travels from air and through the glass prism.

The physical quantity in this case is the refraction of light.
