For a given medium , the speed of light and the polarising angle are V and `i_p` respectively. Then from Brewster's law [C is the speed of light in vacuum ]

Options

A. `V sin i_p=C cos i_p`
B. `C=V cot i_p`
C. `V cos i_p= C sin i_p`
D. `V=C cos i_p`

Answer

A

Explanation

`n= tan i_p =(sin i_p)/(cos i_p) and n=(C)/(V)`
`:. (C)/(V)=(sin i_p)/(cos i_p) " " :. C cos i_p=V sin i_p`
