Which of the following phenomena proves that light waves are transverse waves?
Correct answer: A. Polarization
- A. Polarization
- B. Refraction
- C. Interference
- D. Diffraction
Explanation
Only transverse waves can undergo polarisation. Longitudinal waves cannot undergo polarization. Since light can undergo polarisation, it is a transverse wave. When light waves are polarized, they oscillate in a specific direction or plane. If we place a slit perpendicular to the plane, no polarized light will pass, hence, proving that light is transverse in nature. Hence, A option is the correct option.

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.
