Which cannot be polarized?
Correct answer: D. Sound wave
- A. X-rays
- B. Ultraviolet
- C. Infrared
- D. Sound wave
Explanation
The correct option is D because Sound waves are mechanical longitudinal waves that propagate through a medium by causing particles of the medium to vibrate back and forth in the direction of wave propagation. Sound waves cannot be polarized because polarization refers to the alignment of oscillations in a specific direction, which is not applicable to sound waves.

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.
