Find the angle of flint glass prism which produces the same angular dispersion for `c` and `F` wavelengths in `10^(@)` crown glass prism.
For crown glass : `mu_(F) = 1.5230, mu_( c) = 1.5145`
For flint glass : `mu'_(F) = 1.6637, mu'_( c) = 1.6444`.

Text Solution

Verified by Experts

The correct Answer is:
`4.4^(@)`
As angular dispersion is same.
`:. (mu'_(F) - mu'_(c ))A' = (mu_(F) -mu_( c))A`
`(1.6637 - 1.6444)A' = (1.5230 - 1.5145) xx 10^(@)`
`A' = (0.0085 xx 10)/(0.0193) = 4.4^(@)`
