The refractive indices of flint glass prism for violet, Yellow and Red colours are 1.790, 1.795 and 1.805 respectively, find dispersive power of the flint glass.

Text Solution

Verified by Experts

`mu_(R)=1.790,mu_(Y)=1.795andmu_(V)=1.805`
`omega=(mu_(V)-mu_(g))/(mu_(v)-1)`
= `(0.015)/(0.795)=0.01887`
