Question

Can you ever have a situation in which a light ray goes undeviated through a prism?

Answer 1

Answer:

if we put two prism each other the light ray becomes straight

Answer 2

The prism itself does light rays go undeviated via a prism.

Explanation:

• There's only one case like this. Only if the prism is placed in a medium which has the same refractive index as the prism itself does rays of light go undeviated via a prism.

• The direction of a ray of light going through the prism will still have some minimal deviation.

Light ray:- Light-rays are straight in homogeneous media. We bend across two comparable media at the interface, and can be bent in a medium where the refractive index varies.
