Einstein won the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect" . PARTICLE 1.A particle occupies a well-defined position in space i.e a particle is localized in space e.g. In fact, as you will see on the linked page, matter is also both a wave and a particle.
If light is a particle then it will not be able to diffract after going through an opening or around an obstacle. Based on this evidence, it would seem that light can’t be both a particle and a wave. (N.B. The wave-like nature of light causes the light waves passing through the two slits to interfere, producing bright and dark bands on the screen—a result that would not be expected if light consisted of classical particles. Claiming that it is sometimes a particle and sometimes a wave would be similar to claiming that light is sometimes a thing and at other times not a thing. So light behaves as a wave and as a particle, depending on the circumstances and the effect being observed. a grain of sand, a cricket ball etc. Light has properties of both a particle and an electromagnetic wave but not all the properties of either. First of all, photons have no mass. The energy of a photon depends on its wavelength: longer wavelength photons have less energy and shorter wavelength photons have more. The key difference between wave and particle nature of light is that the wave nature of light states that light can behave as an electromagnetic wave, whereas the particle nature of light states that light consists of particles called photons.. Wave-particle duality is a concept in quantum mechanics.It states that all the particles and quantum entities have not only a wave behaviour but … Depending on which type of experiment is used, light, or any other type of particle, will behave like a particle or like a wave. Light is a wave … and a particle The problems with this approach started with light itself. Light is both a particle and a wave. But when the Mexican wave is over, the crowd or fans are still present in the stadium. Are the two mutually exclusive? This concept is now known as wave-particle duality . Isaac Newton thought light was a particle, but he was at a loss for a way to explain many of its properties, like the way it refracted and split in a prism. At times light behaves as a particle, and at other times as a wave. Photons carry a fixed amount of energy but have no mass. Can we accurately describe light as exclusively a wave or just a particle? This is not the same as refraction, which is when a particle or wave changes direction after going from one medium to another medium.) Classically, light can be thought of in two ways: either as a particle or a wave. Okay for this answer I am going to assume the original assumption is that it isa particle. In the 1600s, French philosopher Rene Descartes became convinced that light was essentially a wave, one that moved through a mysterious substance called plenum.
