Describe biprism exper4iment to calcularte the wavelength of a monocharomatic light. Draw the necessary ray diagram.
If the critical angle of a medium is `sin^(-1)(3/5)`, find the po0larising angle.

Explanation

`C=sin^(-1)(3/5)`
`:." "sin C = (3/5)`
As we know
`mu=1/(sin C)`
`mu=5/3`
`i_(p)=tan^(-1)(5/3)`
`i_(p)=59*03^@`.
