When an unpolarized light of intensity `I_0` is incident on a polarizing sheet, the intensity of the light which dows not get transmitted is

A

`1//2 I_(0)`

B

`1//4I_(0)`

C

zero

D

`I_(0)`

Text Solution

Verified by Experts

The correct Answer is:
A
`I = I_(0)cos^(2) theta`
Intensity of polarised light `= (I_(0))/(2)`
`:.` Intensity of untransmitted light `= I_(0) - (I_(0))/(2) = (I_(0))/(2)`
