Physics Question on Light - Reflection and Refraction
Unpolarised light of intensity 32Wm-2 passes through the combination of three polaroids such that the pass axis of the last polaroid is perpendicular to that of the pass axis of first polaroid. If intensity of emerging light is 3Wm-2 , then the angle between pass axis of first two polaroids is ______º .
Answer
the angle between pass axis of first two polaroids is 30º and 60º.
