Light can be described both as a wave and as a particle. There are two experiments in particular that have revealed the dual nature of light. When we’re thinking of light as being made of particles, these particles are called “photons”. Photons have no mass, and each one carries a specific amount of energy.
A photon (from Ancient Greek φῶς, φωτός (phôs, phōtós) 'light') is an elementary particle that is a quantum of the electromagnetic field, including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless particles that always move at the speed of light ...
1 day ago · Rather than absorbing light continuously from a wave, atoms actually receive energy in packets of light called photons, explaining odd observations such as the existence of a cutoff frequency.

- Has Light Been Seen as Both?
Physicists debated for years whether light was a particle or wave. Isaac Newtonhad argued that light was composed of particles, yet other prominent scientists at the time argued that light was a wave. In 1801, physicist Thomas Young performed the double-slit experiment to determine whether or not light was a particle or wave. The double-slit experi...
Although most scientists had concluded that light was a wave and not a particle after the double-slit experiment, the story was not yet over. In the early 20th century, our understanding of the universe experienced one of its largest shifts in history due to the discovery of quantum mechanics. An entirely new area of physics opened up, and new theo...
The wave-particle duality of light is one of the strangest things about our universe. Although light has been seen as both particle and wave, it has never been seen as both at the same time. Every experiment devised to try and see both has resulted in one or the other. No matter how hard scientists try, light will simply change its behaviour from w...
When a beam of light travels between two media having different refractive indices, the beam undergoes refraction and changes direction when it passes from the first medium into the second. To determine whether the light beam is composed of waves or particles, a model for each can be devised to explain the phenomenon (Figure 3).
Next comes microwaves, then infrared light. Next is the visible spectrum (i.e. the different colors of light that people can see), followed by ultraviolet light. Then waves with higher frequency are called X-rays and still higher are gamma rays - these have the peaks closest together. Sometimes you'll hear that light is made of photons.

Jun 29, 2020 · The "particle" nature of light is a whole different subject but tl;dr: light is a wave with quantized energy levels which are in a certain modern way called "particles". Light isn't made of particles as you think for water waves and sound waves, we just call the energy packets of the wave "particles". To understand why we do that there is a lot ...
