A beam of unpolarized light of intensity I0 is passed through a polaroid A and then through another polaroid B which is oriented so that its principal plane makes an angle of 45° relative to that of A. The intensity of the emergent light is :
- I0
- \(\frac{I_{0}}{2}\)
- \(\frac{I_{0}}{4}\)
- \(\frac{I_{0}}{8}\)
Answer
(C) I_ 0 4
