But all behavior of light can be explained by combining the two models: light behaves like particles and light behaves like waves. It’s not as odd as it might seem, either. Particles and waves are sometimes conceived as opposites, but they’re not. Also, light is not the only thing that exhibits behavior of both particles and waves.
1 day ago · "Light is not sometimes a particle and sometimes a wave," he said. "It is always both a wave and a particle. It's just that we highlight one of the properties depending on which experiment we do."
Mar 12, 2024 · where \(h\) is a constant with the value \(6.63\times10^{-34}\ \text{J}\cdot\text{s}\). Note how the equation brings the wave and particle models of light under the same roof: the left side is the energy of one particle of light, while the right side is the frequency of the same light, interpreted as a wave. The constant \(h\) is known as ...

The problem with this wave-particle duality is that language has issues accommodating both behaviors coming from the same object. After all, language is built of our experiences and emotions, of the things we see and feel. We do not directly see or feel photons. We probe into their nature with experimental set-ups, collecting information through mo...
In 1924, Louis de Broglie, a historian turned physicist, showed quite spectacularly that the electron’s step-like orbits in Bohr’s atomic model are easily understood if the electron is pictured as consisting of standing waves surrounding the nucleus. These are waves much like the ones we see when we shake a rope that is attached at the other end. I...
De Broglie’s remarkable idea has been confirmed in countless experiments. In college physics classes we demonstrate how electrons passing through a crystal diffract like waves, with superpositions creating dark and bright spots due to destructive and constructive interference. Anton Zeilinger, who shared the physics Nobel prize this year, has champ...
Dec 12, 2013 · When waves come into contact with one another, they exhibit interference: waves that are all in phase (rarefying or compressing the same particles at the same time) add together to become stronger ...
We have long known that EM radiation is like a wave, capable of interference and diffraction. We now see that light can also be modeled as particles—massless photons of discrete energy and momentum. We call this twofold nature the particle-wave duality, meaning that EM radiation has properties of both particles and waves. This may seem ...

May 11, 2022 · So light, and all other electromagnetic radiation, is now recognised as something rather strange: it propagates as if it is a wave, but interacts with matter as if it is a stream of particles. In truth, it is neither a wave nor a particle, but it is convenient to describe its behaviour in terms of one or the other, as the situation dictates.
