A beam of natural light falls on a system of 6 polaroids, which are arranged in succession such that each polaroid is turned through `30^@` with respect to the preceding one. The percentage of incident intensity that passes through the system will be

A

1

B

0.5

C

0.3

D

0.12

Text Solution

Verified by Experts

The correct Answer is:
D
Final Intensity
`I= (I_(0))/(2)(cos^(2)theta)^(5)`
`implies (I)/(I_(0))= (1)/(2) xx ((sqrt(3))/(2))^(10)= 0.12`
