The refractive index of glass is 1.520 for red light and 1.525 for blue light. Let `delta_(1) and delta_(2)` angles of minimum deviation for red and blue light respectively in a prism of this glass, then

Options

A. `delta_(1)`. Can be less than or greater than `delta_(2)` depending upon the values of `delta_(1) and delta_(2)`
B. `delta_(1) gt delta_(2)`
C. `delta_(1) lt delta_(2)`
D. `delta_(1) = delta_(2)`

Explanation

`delta_(1) = (mu_(R)-1) A, delta_(2) = (mu_(beta - 1)A`
As. `mu_(R) lt mu_(B) " " therefore delta_(1) lt delta_(2)`
