Optics Question 469
Question: Two Nicols are oriented with their principal planes making an angle of $ 60{}^\circ $ . 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:
[c] Intensity of polarized light form first polarizer $ =\frac{100}{2}=50% $
$ I=50{{\cos }^{2}}60{}^\circ =\frac{50}{2}=12.5% $
