The sunlight after passing through a Polaroid is:
Correct answer: A. Polarized
- A. Polarized
- B. Partially polarized
- C. Unpolarized
- D. Longitudinal waves
Explanation
The correct option is A because A Polaroid is a type of polarizing filter that selectively transmits light waves that are oscillating in a particular direction while blocking light waves oscillating in other directions. When sunlight passes through a Polaroid, it undergoes polarization, meaning its vibrations become aligned in a particular direction.

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.
