Question

When a beam of white light passes through a prism it gets a) Reflected b) deviated and dispersed c) only deviated

Answer 1

first you should what is deviation and dispersion in case of prism ?
deviation of prism :- when a ray of light enters the transparent material, the ray's direction is deflected. A beam passing through prism  is deflected twice : once entering, and again when exiting. The sum of these two deflections is called the deviation angle.

dispersion :- when a beam of light enters a glass prism, which has non parallel sides.light splits into its constituents wavelengths.this phenomena is known as dispersion of light.

from above explanation , you can say that when a beam of light passes through a prism it gets deviated and dispersed.

hence, (b) is correct

Answer 2

Answer:

the answeris b as of what I knew
