Respuesta :
The refraction occurs because when the light beam hits the prism, it is bent and light ricochets and the light is sometimes separated into the different colors.
Explanation:
Refraction: It is the phenomenon in which the light rays get bend while travelling from one medium to the another medium. It is due to change in the speed of the light.
The light rays get bend towards the normal while travelling from rarer medium to the denser medium.
The light rays get bend away from the normal while travelling from denser medium to the rarer medium.
When light passes through lenses and through a set of prism then refraction will take place as the light is travelling from rarer medium (air) to the denser medium (prism or lens). It is due to change in the speed of the light.
