Question

Assertion angle of deviation depends on the angle of prism.
Reason For thin prism =`(mu-1)A`
Where =angle of deviation
`mu=refractive index, A=angle of prism
A. Both assertin and reason are true and reason is the correct explanation of assertion
B. Both assertion and reason are true but reason is not the correct explanation of assertion
C. Assertion is true but reason is flase
D. Both assertion and reason are false

Answer 1

Correct Answer - A
The relation between angle of dieviation `delta` for a thin prism an angle of prism and refractive index `(mu)` of material of prism is given buy `delta = (mu-1)A`
