A person finds that the sun rays reflected by the still surface of water in a lake are polarized. If the refractive index of water is 1.327 the sun will be seen at the angle of .... with the horizon

Options

A. `57^(@)`
B. `75^(@)`
C. `37^(@)`
D. `53^(@)`

Answer

C

Explanation

Using Brewster.s law.
`n= tan theta_(p)`
`1.327= tan theta_(p)`
`:. theta_(p)=53^(@)`
Angle made by the sun with the horizon
`=90^(@)-theta_(p)`
`=90^(@)-53^(@)`
`=37^(@)`
