The nature of light is one of the most fundamental topics in physics. Light cannot be explained by wave nature alone. Wave theory explains reflection refraction interference and diffraction but FAILS to explain photoelectric effect and Compton effect. Particle nature alone cannot explain interference diffraction and polarization which require wave properties. Light has dual nature meaning it behaves as both a wave and a particle (photon) depending on the experiment. Wave nature explains: reflection refraction interference diffraction polarization. Particle nature explains: photoelectric effect Compton effect pair production. This wave-particle duality was established through work of Maxwell (EM wave theory) Einstein (photoelectric effect photon theory) and de Broglie (matter waves). Light definitely has measurable wave and particle properties. Saying it has neither nature would contradict all of modern physics including the technology behind lasers solar cells and fibre optics.
FAQ
Common questions and clear answers for this topic.
Optics is the branch of physics that studies the behavior of light, including its reflection, refraction, and interaction with lenses and mirrors.
Reflection is the bouncing back of light when it strikes a surface, while refraction is the bending of light as it passes from one medium to another with a different optical density.
A lens is a transparent optical device with curved surfaces that refracts light to converge or diverge rays, commonly classified as convex (converging) or concave (diverging).
The speed of light in a vacuum is approximately 3 x 10^8 meters per second, denoted by the symbol c.
Total internal reflection occurs when light traveling from a denser medium to a rarer medium strikes the boundary at an angle greater than the critical angle, causing it to be completely reflected back into the denser medium.
