To verify that the light beam is either unpolarized or circularly polarızed one requires to use (A) a half wave plate and a polarizer (B) a quarter wave plate (C) a quarter wave plate and half wave plate (D) a quarter wave plate and a polarizer
quarter wave plate, bcz on passing circularly polarised light through quarter wave , it changes to linearly polarised light but unpolarised light remain same on passing through it.
When a circularly polarized wave passes through a quarter wave plate it becomes linearly polarized and if a polarizer is kept with its axis perpendicular to polarization it will b...
a quarter wave plate and a polarizer. because half wave plate will convert the circularly polarized into plane polarized but it doesn't do anything with unpolarized light. now you ...
