Question

Assertion : Angle of deviation depends on the angle of prism.
Reason: For thin prism, $\delta = (\mu - 1) A$.

• A. If both assertion and reason are true and reason is the correct explanation of assertion
• B. If both assertion and reason are true but reason is not the correct explanation of assertion
• C. If assertion is true but reason is false
• D. If both assertion and reason are false

Answer 1

Answer: (A)

For a thin prism, the relation between angle of deviation, $\delta$, angle of prism A and refractive index $\mu$ is $\delta = ( \mu - 1) A$
