it is called a photon
Proton is a positive particle and electron is a negative particle.
Very small...very small indeed.
An electron.
The lightest known subatomic particle is the neutrino. Neutrinos have very small or even zero mass, making them incredibly light. They are electrically neutral and interact very weakly with other particles, making them difficult to detect.
No, it is not a hypothesis. Photons are the fundamental particle of light, characterized by properties like wave-particle duality and energy quantization. This concept is well-supported by experimental evidence in the field of quantum physics.
During the life of Isaac Newton, there was a huge scientific debate between proponents of the wave model of light and the particle model of light. This was resolved in the 20th century by quantum mechanics which showed that light is both a particle and a wave.
The more appropriate question would be Is light a particle or a wave? But first, lets answer your question.. Light is both an energy and a particle..... The Energy liberated by a light can be given by E=hc/lamda where c is the speed of the light and landa is the wavelength of the light. Now to my question.. Light is both a particle and a wave... Light travels in straight lines..... How does it travel???? Through particles.. the light particles transfer the light energy by rapid vibration as in case of sound energy.... How it is a wave..?? This was proved by Albert Einstein, When we consider a very small body, when i say very small. i mean not visible from naked eyes,,, light tends to curve alont the body,, (This particular phenomenon is given a special name, sorry, i forgot.)Thus, light can also be treated as a wave.
everything is both a wave and a particle. consider a Baseball, we see it as only a particle because its wavelength is much too small to observe.
Positron
A particle is a very small bit of solid drop of liquid
particle
The particle nature of light, as described by the photon theory, cannot be fully explained by the wave model of light. The wave model also cannot account for certain phenomena such as the photoelectric effect and the behavior of light in very small scales, which require a particle-like description of light.
