The transverse nature of light is shown by
Correct answer: C. Polarization of light
- A. Interference of light
- B. Refraction of light
- C. Polarization of light
- D. Dispersion of light
Explanation
A light wave is an electromagnetic wave which travels through the vacuum of outer space and transparent materials like glass. Electromagnetic waves are transverse waves in the sense that the plane of the wave vibrations is different from the plane of wave propagation. The electromagnetic waves in the true sense have the direction of propagation perpendicular to the direction of its electric and magnetic fields. In the case of polarized waves, the electric and magnetic fields are also at right angles to each other. Polarized light waves are electromagnetic waves in which the vibrations occur in a single plane. Light can be polarized by transmission, reflection, refraction or scattering. Using a polaroid filter, different planes of vibration of polaroid filters can be blocked due to the special material used there. Due to the polarization of light, it is evident that light is a transverse wave.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
