When light of particular wavelength fall...

When light of particular wavelength falls on a plane surface at an angle of incidence `60^(@)` then the reflected light becomes completely plane polarized Find the refractive index of surface material and the angle of refraction through it.

Text Solution

Verified by Experts

Using Brewster.s law
`mu=tan i_p`
=`tan 60^@`
`=sqrt3`
At this condition `i_p+r=90^@`
`therefore r=90^@-60^@`
`=30^@`
