Which of the following waves cannot be polarized?
Correct answer: B. Ultrasound
- A. Radio waves
- B. Ultrasound
- C. Ultraviolet
- D. X-rays
Explanation
"Ultrasound" waves are longitudinal in nature, hence they cannot be polarized. Only transverse waves like electromagnetic waves can be polarized.

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.
