In the context of polaroids, when three polaroids (I, II, and III) are aligned as described, under what circumstances will light emerge from polaroid (II) if the pass axis of polaroid (III) is not parallel to either polaroid (I) or (II)?
Options
- ALight will always emerge from polaroid (II)
- BNo light will emerge from polaroid (II) under any circumstances
- CLight will emerge from polaroid (II) only when the pass axis of (III) is perpendicular to (I) or (II)
- DLight will emerge from polaroid (II) only when the pass axis of (III) is parallel to (I) or (II)
Correct answer
C. Light will emerge from polaroid (II) only when the pass axis of (III) is perpendicular to (I) or (II)
Step-by-step solution
Correct Option is : (C) Light will emerge from polaroid (II) only when the pass axis of (III) is perpendicular to (I) or (II)
