Ans. (a) 96. Unpolarized light is incident on a combination ofa polarizer, a A/2 plate and a a/4 plate kept one after the other. What will be the output polarization for the following configurations? Configuration 1: Axes of the polarizer, the ,/2 plate and the A/4 plate are all parallel to each other. Configuration 2: The /2 plate is rotated by 45° with respect to configuration 1. Configuration 3: The A/4 plate is rotated by 45° with respect to configuration 1. (a) Linear for configuration 1, linear for configuration 2, circular for configuration 3. (b) Linear for configuration 1, circular for configuration 2, circular for configuration 3. (c) Circular for configuration 1, circular for configuration 2, circular for configuration 3 (d) Circular for configuration 1, linear for configuration 2, circular for configuration 3.
