The photoelectric effect was proposed by Einstein. Albert Einstein, in 1905, explained the phenomenon where photons of light eject electrons from a material’s surface. This theory helped establish the concept of quantized energy of light and the particle-like nature of ...

Young, first showed that diffraction of light waves occurs. Thomas Young conducted the double-slit experiment in the early 19th century, demonstrating interference patterns that confirmed light’s wave nature. This experiment provided fundamental evidence for the wave theory of light, showing ...
The electromagnetic nature of light was discovered by Maxwell. James Clerk Maxwell, a Scottish physicist, formulated the theory of electromagnetism in the 19th century. He unified electricity and magnetism into a single set of equations known as Maxwell’s equations, predicting ...
The transverse nature of light waves is confirmed based on the phenomenon of polarization. Polarization demonstrates that light waves oscillate perpendicular to their direction of propagation. This is distinct from longitudinal waves, confirming that light behaves as a transverse electromagnetic ...
The wave theory of light was proposed by Huygens. Christiaan Huygens, a Dutch physicist and mathematician, put forth the idea in the late 17th century. He suggested that light propagates as a wave through a medium called the luminiferous aether, ...
