Question

What are the factors that determine the angle of deviation in a prism?

• A. angle of incidence
• B. wave length
• C. angle of the prism
• D. all the above

Answer 1

Answer: (D)

all the above

Answer is D
The angle between the incident ray and the emergent ray, when a ray suffers refraction through the optical prism is called angle of deviation.
The angle of deviation of the prism depends on the following factors.

• Angle of prism
• Angle of incidence
• Wavelength of the light
• Refractive index of the optical material, that is, prism

Hence, all the options are right.
