Light on passing through a Polaroid is ___________________?
Correct answer: A. plane polarized
- A. plane polarized
- B. un-polarized
- C. circularly polarized
- D. elliptically polarized
Explanation
A Polaroid transmits vibrations mainly along one transmission axis and absorbs the perpendicular component, so unpolarized light emerging from it becomes plane-polarized. The likely wrong choice is b because the incoming light may be unpolarized, but the transmitted light is not.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
