In dispersion of white light due to a triangular glass prism, the deviation of red colour is less compared to violet colour. The reason …

is `n_(v) gt n_(r)`

is `n_(r) gt n_(v)`

is `n_(v) = n_(r)`

does not depend on n.

Text Solution

Verified by Experts

In glass medium, speed of violet colour is less as compared to speed of red colour. So, ` n_(v) gt n_(r) ` from `n= (c )/(v)`.
