Explain why it is not advisable to use small values of incident ray in performing experiment on the refraction through a glass prism.

As we know that when light incident on a glass prism then few amount of the light is absorbed by the prism and then the remaining amount of light gets refracted out of the prism on the other side.

In this whole experiment of the prism we know that the amount of light absorbed by the prism completely depends on the material and in order to find the phenomenon of refraction through prism we required a good amount of light to be incident on the prism.

Because if we took small amount of light the the refracted light that comes out of prism is very small to detect the complete phenomenon of refraction.

This is the reason why it is not advisable to use small values of incident ray in performing experiment on the refraction through a glass prism.
