A horizontal beam of vertically polarized light of intensity `43 W//m^(2)` is sent through two polarizing sheets. The polarizing direaction of the first is `60^(@)` to the vertical, and that of the second is horizontal. The intensity of the light transmitted b y the pair of sheets is (nearly)

A

`8 . 1 W // m^(2)`

B

` 7 . 3 W // m^(2)`

C

` 6 . 4 W // m^(2)`

D

`3 . 8 W // m^(2)`

Text Solution

Verified by Experts

The correct Answer is:
