If D is the deviation of a normally fall...

If D is the deviation of a normally falling light beam on a thin prism of anlge A and `omega` is the dispersive power of the same prism then

A

`delta` is independent of refractive index

B

`omega` is independent of refractive index

C

`omega` is independent of A

D

`delta` is independent of A

Text Solution

Verified by Experts

The correct Answer is:
C
For a small prism , `delta = A(n-1)`
i.e. `delta` depends upon A and refractive index n
Similarly , the dispersive power depends upon n but it is independent of A .
