The angle of minimum deviation for a prism is `40^(@)` and the angle of the prism is `60^(@)`. The angle of incidence in this position will be

A

Less than `41^(@)`

B

Equal to `41^(@)`

C

More than `41^(@)`

D

None of the above

Text Solution

Verified by Experts

The correct Answer is:
C
`delta_(m) = 2i - A `
`rArr i= (A + delta_(m))/(2) = (100)/(2) = 50^(@)` .
