The transverse nature of light is verified with the phenomenon of:
Correct answer: B. Polarization
- A. Interference
- B. Polarization
- C. Diffraction
- D. Dispersion
Explanation
The phenomenon of polarization is used to verify the transverse nature of light. Transverse waves are characterized by oscillations that are perpendicular to the direction of wave propagation. In polarization, light waves are filtered so that they vibrate in only one plane. This filtering process confirms that light waves oscillate in planes perpendicular to their direction of travel, hence proving their transverse nature.Other options like interference, diffraction, and dispersion involve light behaving as a wave but do not specifically demonstrate the transverse nature. Interference and diffraction deal with the superposition and bending of waves, while dispersion involves the separation of light into different colors. None of these directly show that light is transverse.

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.
