Question

The optical phenomenon which exclusively demonstrates the transverse nature of light waves, thereby distinguishing them from longitudinal sound waves, is

Professor PC Thomas Classes · Answer

(c) : General wave phenomena like interference, diffraction, and refraction are common to all types of waves (both transverse and longitudinal, including sound). However, polarization is defined as the restriction of the vibrations of a wave entirely to a single plane. This geometric restriction is physically possible only for transverse waves, where vibrations occur perpendicular to the direction of propagation. Thus, polarization proves the transverse nature of light.
