The refractive indices of flint glass fo...

The refractive indices of flint glass for red and violet lights are 1.613 and 1.632, respectively. Find the angular dispersion produced by a thin prism of flint glass having refracting angle `5^@`.

Text Solution

Verified by Experts

Angle of dispersion:
`delta_(v)-delta_(r)=(mu_(v)-mu_(r))A`
`=(1.632-1.613)5=0.095^@`
