Is the photon a particle or a wave?
light
Einstein believed light is a particle (photon) and the flow of photons is a wave. The main point of Einstein’s light quantum theory is that light’s energy is related to its oscillation frequency.
What is the nature of photon?
A photon has a zero mass, i.e. it is massless. It is a stable particle. Photons can be created or destroyed when radiation is emitted or absorbed. The total energy and momentum are conserved during a photon-electron collision….Photons:

Is a photon a particle or energy?
Secondly, the photon is now thought of as a particle, a wave, and an excitation—kind of like a wave—in a quantum field. A quantum field, such as the electromagnetic field, is a kind of energy and potential spread throughout space. Physicists think of every particle as an excitation of a quantum field.
Can a photon be a wave?
The photon is typically described as an electromagnetic (EM) wave, such as the image below. These are the two components of the wave (longitudinal and transverse). Longitudinal waves constantly flow from particles, causing an electric field even when a particle is not in motion.
What is wave nature and particle nature?
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.
Is photon a wave or particle class 12?
Photons are bosons, considered by the subatomic particles, with no electric charge or resting mass and one unit of spin; they are field particles that are assumed to be electromagnetic field carriers.
Is a photon a point particle?
According to Quantum Mechanics, a photon, like any other point particle, has no size at all. It is a point, if treated as a particle.
Why are photons considered particles?
Scientists call a particle of light a photon because it can carry and pass on energy like matter can, but it also sometimes acts like a wave, as light should. Since a photon is a particle that has very unique abilities that normal matter does not have, we can say that light is not matter.
Is a photon an elementary particle?
The photon is a type of elementary particle, the quantum of the electromagnetic field including electromagnetic radiation such as light, and the force carrier for the electromagnetic force (even when static via virtual particles).
How are photons created and destroyed?
The simplest answer is that when a photon is absorbed by an electron, it is completely destroyed. All its energy is imparted to the electron, which instantly jumps to a new energy level. The photon itself ceases to be.
What is the energy of a photon?
The energy of a single photon is a small number because the Planck constant is ridiculously tiny. The energy of a single photon of green light of a wavelength of 520 nm has an energy of 2.38 eV. You can use the photon energy calculator to further explore the relationship between the photon energy and its frequency or wavelength.
