The first person to demonstrate that diffraction of light waves occurs was Young (Option [B]). Thomas Young, an English scientist, conducted the famous double-slit experiment in the early 19th century. In this experiment, he observed interference patterns produced by light passing through two closely spaced slits, providing direct evidence of light behaving as a wave. Diffraction patterns formed when light waves passed through small openings or around edges, demonstrating wave-like characteristics such as interference and diffraction.
Option [A], Gramaldi, is not associated with contributions to optics or light phenomena. Option [C], Maxwell, formulated Maxwell’s equations describing electromagnetism. Option [D], Foucault, made significant contributions to optics and physics, but he is known for his work on the speed of light and pendulum experiments.
Therefore, Thomas Young’s double-slit experiment established the phenomenon of light diffraction, crucial in demonstrating that light exhibits wave properties, laying the groundwork for the wave theory of light and advancing our understanding of optics and wave behavior.

The electromagnetic nature of light was discovered by Maxwell (Option [C]). James Clerk Maxwell, a Scottish physicist, formulated Maxwell’s equations in the mid-19th century. These equations unified electricity and magnetism, predicting the existence of electromagnetic waves, including light. Maxwell demonstrated that light is an electromagnetic wave propagating through space at the speed of light, and his work laid the foundation for understanding the fundamental relationship between electricity, magnetism, and light.
Option [A], Snell, is known for Snell’s law of refraction, describing how light bends when passing through different materials. Option [B], Newton, proposed the corpuscular theory of light, suggesting light as a stream of particles. Option [D], Young, conducted experiments demonstrating the wave nature of light through his double-slit experiment, contributing to the understanding of light as waves.
Thus, James Clerk Maxwell is credited with discovering the electromagnetic nature of light, revolutionizing physics with his unified theory of electromagnetism.

The transverse nature of light waves is confirmed based on the phenomenon of polarization (Option [C]). Polarization refers to the orientation of the electric field component of light waves as they propagate. When unpolarized light passes through a polarizing filter, only the component of the electric field aligned with the filter’s polarization axis can pass through, demonstrating that light waves oscillate perpendicular to their direction of propagation.
This behavior aligns with the characteristics of transverse waves, where oscillations occur perpendicular to the wave’s direction of travel. Polarization effects are observed in various optical phenomena, including glare reduction, 3D movie viewing with polarized glasses, and the study of light interaction with materials such as crystals.
While interference (Option [B]), double refraction (Option [A]), and reflection (Option [D]) also demonstrate various properties of light waves, they do not directly confirm the transverse nature of light waves as conclusively as polarization does. Therefore, polarization stands out as the phenomenon that unequivocally supports the transverse wave nature of light.
The wave theory of light was proposed by Huygens (Option [B]). Christiaan Huygens, a Dutch scientist, introduced this theory in the late 17th century. He postulated that light propagates as a wave through a medium known as the luminiferous aether. Huygens' wave theory provided explanations for phenoRead more

He postulated that light propagates as a wave through a medium known as the luminiferous aether. Huygens’ wave theory provided explanations for phenomena such as reflection, refraction, and diffraction, which could be understood based on the principles of wave interference and superposition.
Sir Isaac Newton (Option [A]), on the other hand, initially proposed a corpuscular theory of light, where he described light as a stream of particles. This theory had difficulty explaining certain optical behaviors but gained traction due to Newton’s reputation.
Options [C] Planck and [D] Faraday were influential in other areas of physics, particularly in quantum theory and electromagnetism, respectively, but they did not propose the wave theory of light.
Thus, Huygens is credited with pioneering the wave theory of light, which laid the foundation for modern understanding of light as an electromagnetic wave.

Light waves are classified as transverse waves (Option [A]). Transverse waves are characterized by oscillations perpendicular to the direction of energy transfer. In the case of light, electric and magnetic fields oscillate perpendicular to the direction of propagation. This wave behavior is governed by Maxwell’s equations in classical electromagnetism.
Light waves do not exhibit longitudinal wave characteristics (Option [B]), where oscillations occur parallel to the direction of energy transfer. Longitudinal waves involve compressions and rarefactions, typical of sound waves traveling through air or other mediums.
Therefore, light waves are fundamentally transverse electromagnetic waves. They propagate through vacuum at the speed of light (approximately 3 × 10^8 meters per second) and can travel through transparent materials such as glass or water. The transverse nature of light waves allows for phenomena like polarization, interference, diffraction, and refraction, which are essential in optics and the study of light behavior. Thus, Option [A], transverse wave, accurately describes the wave nature of light.
