Light can be polarized by:
Correct answer: A. Reflection
- A. Reflection
- B. Refraction
- C. Diffraction
- D. Interference
Explanation
This is the correct answer. Light can be polarized by reflection, especially when it reflects off a non-metallic surface at a specific angle known as Brewster's angle. At this angle, the reflected light becomes completely polarized, with the electric field vector vibrating in a plane parallel to the reflecting surface.

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.
