Question

b) Plot delta vs i graph for rays of light refracting through a glass prism.​

Answer 1

Answer:

When light travels from one medium to another medium, it is refracted and enters the new medium at a different angle. 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.

i is the angle of incidence.

r is the angle of refraction.
