Polarization supports the wave theory of light by demonstrating that light behaves as a transverse wave, which can oscillate in different directions. When light is polarized, it shows that the waves can vibrate in a specific plane rather than in all directions, aligning with the characteristics of wave behavior. This phenomenon is consistent with the predictions of the wave theory, as it explains the interaction of light with materials that filter or absorb certain orientations of light waves. Therefore, polarization provides compelling evidence that light exhibits wave-like properties.
Properties of light that can be best explained by the wave theory include interference, diffraction, and polarization. Wave theory describes how light waves can interact with each other to produce interference patterns, how they bend around obstacles and spread out when passing through small openings (diffraction), and how their oscillations can be oriented in specific directions (polarization).
A polarization experiment demonstrates that light is a transverse wave composed of oscillating electric and magnetic fields perpendicular to the direction of propagation. It also shows that light waves are polarized, meaning the electric field oscillates in a specific orientation. This experiment helps to study the wave nature of light and confirm the wave theory of light propagation.
Huygens' wave theory of light cannot explain phenomena like polarization and interference accurately. It also fails to predict some experimental observations, such as the photoelectric effect. Additionally, the theory could not fully account for the speed of light in a vacuum.
The polarization of light is best supported by the wave model of light, which describes light as an electromagnetic wave with oscillating electric and magnetic fields perpendicular to the direction of propagation. In the wave model, polarization occurs when the electric field oscillates in a specific orientation, leading to light waves that are aligned in a particular way. This model explains how polarizing filters can selectively block certain orientations of light waves, demonstrating the wave-like nature of light.
A half wave plate changes the orientation of the polarization of light by rotating it by 90 degrees.

The Compton effect supports the particle theory of light, as it demonstrates that photons (particles of light) can interact with matter like particles and exhibit particle-like behavior by transferring momentum to electrons during scattering. This is not consistent with the wave theory of light, which views light as a continuous wave rather than individual particles.
Light demonstrates wave characteristics when it undergoes phenomena such as interference, diffraction, and polarization. These behaviors are consistent with light behaving as a wave rather than a particle.
A wave plate is an optical device that changes the polarization of light. It does this by altering the phase difference between the two perpendicular components of light waves. This change in phase causes the light to be polarized in a specific direction when it passes through the wave plate.
The photoelectric effect does not support the wave nature of light. This phenomenon can only be explained by the particle nature of light, as described by Albert Einstein in his theory of photons.
Thomas Young is the scientist who proposed in 1801 that light is a wave, using his double-slit experiment to support this theory.
mode theory assumes light to be a wave, but ray theory does not assume light to be either a wave or particle. ray theory is used to calculate properties like magnification or distance to the object or image in an optical system, where as mode theory is used find bandwidth, reflection coefficients and parallel polarization.
