The term "angle of deviation" is used in reference to a/an A. lens. B. polarizer. C. analyzer. D. prism.

Option (D)

Explanation:

The angle of deviation occurring in the prism is usually defined as an angle between the incidence angle and the refraction angle formed by the ray that penetrates through the prism surface between one medium to another having a separate refractive index.

It is usually considered as the smallest angle through which light propagates and gets bent due to the presence of an optical system.

Thus, the term "angle of deviation" is used in reference to the prism.

Therefore, the correct answer is option (D).
