Question

the aim experiment is to find the refractive index of prism​

Answer 1

Answer:

This angle depends only on the index of refraction of the prism and the angle between the two has to be maintained until the experiment is over, so as not to refocus again.

Answer 2

The degree of bending of the light's path depends on the angle that the incident beam of light makes with the surface of the prism, and on the ratio between the refractive indices of the two media. This is called Snell's law. where, n is the refractive index of the material of the prism.
