Technically light is not a particle nor a wave, due to particle-wave duality. However it is commonly referred to as a particle, the photon. Then again, there is also the photon field in which photons live, so the entire picture is somewhat complicated.
One of the major signs that light had some particle-like qualities came from the photo-electric effect (which incidentally landed Albert Einstein his Nobel prize). The photo-electric effect happens when high energy photons (or high frequency light if you like) strikes a metal and the light evicts an electron from the metal.
What was surprising is that the amount of released electrons dropped to zero below a certain frequency. But increasing the frequency much above that threshold likewise did not lead to additional released electrons, it only increased the energy of these so-called photo-electrons. Increasing the intensity of the light does increase the number of released electrons, but it does not increase the energy of the photo-electrons.
This was very counter-intuitive for people who regarded light as being just a wave because increasing the intensity should increase the energy and thus also the energy of the released electrons.
Through the work of Einstein we now know that increasing the intensity increases the number of photons in the light beam, and more photons means more collisions to release electrons. But each photon does not gain more energy with increased intensity (you just get more protons) which explains why the energy of the released electrons was insensitive to the intensity of the light.
With the advent of quantum mechanics it is now clear that the electromagnetic field is quantized; it comes in small packages called photons.
What else can I help you with?
Is light a particle?
Yes. Light has both particle and wave properties.
Is light both a wave and a particle?
Yes, light exhibits properties of both a wave and a particle, known as wave-particle duality.
When light behaves like a particle what is the particle called?
When light behaves like a particle, it is called a photon. Photons are the fundamental particles of light and carry energy and momentum.
What is a single particle of light called?
A single particle of light is called a photon. Photons are the basic unit of light and do not have mass.
A particle scatters light if it is larger than the of light?
A particle scatters light if it is larger than the wavelength of light. This is because scattering occurs when the size of the particle is comparable to or larger than the wavelength of the light waves it interacts with, causing the light to be redirected in different directions.
Proofs of the particle nature of light?
Albert Einstein's Photo-electric effect is one of the proof of the particle nature of light. The experiment on the wave particle duality is another proof pf the particle nature of light.
What are the proofs of the particle nature light?
The particle nature of light is illustrated by the photoelectric effect.
Is light a particle?
Yes. Light has both particle and wave properties.
Is light both a wave and a particle?
Yes, light exhibits properties of both a wave and a particle, known as wave-particle duality.

What is a single particle of light called?
A single particle of light is called a photon. Photons are the basic unit of light and do not have mass.

A particle scatters light if it is larger than the wavelength of light. This is because scattering occurs when the size of the particle is comparable to or larger than the wavelength of the light waves it interacts with, causing the light to be redirected in different directions.
Does light behave as a wave or a particle in chemistry?
Light behaves as both a wave and a particle in chemistry. As a wave, light exhibits properties such as interference and diffraction, while as a particle, light consists of discrete packets of energy called photons. This dual nature of light is described by the wave-particle duality principle.
What happens when a particle goes through a light bulb?
When a particle passes through a light bulb, it interacts with the atoms in the filament of the bulb. This interaction can cause the particle to lose energy, which results in the emission of light. The emitted light is what we perceive as the light produced by the light bulb.
What is the effect you can see when light is bouncing from a particle?
When light bounces off a particle, it can cause the particle to scatter light in different directions, leading to effects like diffraction, interference, and reflection. These interactions can provide information about the size, shape, and composition of the particle.
What discovery resulted from the photoelectric effect?
The discovery resulting from the photoelectric effect was that light can behave as both a wave and a particle. This finding led to the development of the quantum theory of light, which laid the foundation for quantum mechanics.
Is a light particle called a photon?
Yes, a light particle is called a photon. Photons are the basic unit of light and electromagnetic radiation.
