A beam of light travelling in water fall...

A beam of light travelling in water falls on a glass plate immersed in water. When the incidence angle is `51^(@)`, then the reflected beam of light is found polarized. Calculate `mu` of glass. Given `mu` of water is `4//3`.

Text Solution

Verified by Experts

The correct Answer is:
`1.65`
`tan i_(p) = "" g mu ^(omega) = (mu "of glass")/(mu " of water")`
`:. mu` of glass ` =mu ` of water `xx tan i_(p)`
`= (4)/(3) xx tan 51^(@) = (4)/( 3) xx 1.2349 = 1.647`
