The phenomenon of polarization of light reveals that light waves are:
Correct answer: A. Transverse waves
- A. Transverse waves
- B. Longitudinal waves
- C. Mechanical waves
- D. None of these
Explanation
The phenomenon of polarization of light reveals that light waves are transverse waves.Transverse waves are characterized by vibrations that are perpendicular to the direction of wave propagation. In the case of polarized light, the electric field vector oscillates in a plane perpendicular to the direction of the wave's propagation, demonstrating the transverse nature of light waves. This is in contrast to longitudinal waves, where the vibrations are parallel to the direction of wave propagation, and mechanical waves, which require a medium (like air, water, or a solid) to propagate and also involve particle motion in the direction of the wave. Light, including visible light, is an example of an electromagnetic wave, and it exhibits transverse wave behavior.

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.
