Question: Two Nicols are oriented with their principal planes making an angle of 60°. The percentage of incident unpolarized light which passes through the system is
Options:
A) 50%
B) 100%
C) 12.5%
D) 37.5%
Show Answer
Answer:
Correct Answer: C
Solution:
Intensity of polarised light from first polarizer $ =\frac{100}{2}=50 $
$ I=50{{\cos }^{2}}60{}^\circ =\frac{50}{4}=12.5 $
