That theory states that light behaves as group of particles.
Nowhere. A photon must travel at the speed of light so it starts with that speed when it is created. This is the origin of the theory of special relativity.
this is a much more complicated question than perhaps you realise. try looking up "wave particle duality" photons have the strange characteristic of haveing properties of both a wave and a particle.
Some theories about light include the electromagnetic theory, which describes light as an electromagnetic wave, and the quantum theory of light, which views light as both a wave and a particle called a photon. The theory of special relativity also plays a role in understanding the behavior of light.
Photon do not exist in reality. Newton's Corpuscular Theory of light ASSUMES an imaginary particle PHOTON to explain various phenomena of light.
Albert Einstein was the scientist who hypothesized that light can behave as a particle called a photon in his theory of the photoelectric effect, for which he was awarded the Nobel Prize in Physics in 1921.
Newton's corpuscular theory Huygen's mechanical wave theory Maxwell's electromagnetic wave theory Finally Planck's quantum theory LIght as a single "photon" acts somewhat differently than a wave (of energy).
A packet of light energy is called a photon.
A photon is formed when an electron transitions to a lower energy level within an atom or molecule, releasing energy in the form of electromagnetic radiation. This energy is carried by the photon as a discrete particle-like bundle of electromagnetic radiation.
The concept of a photon was first introduced by Albert Einstein in 1905 as part of his theory of the photoelectric effect. However, the term "photon" was coined later by physicist Gilbert N. Lewis in 1926.
A photon of yellow light has lower frequency that a photon of violet light. Remember that light can be considered both as particles (photons) and as waves. So when saying a photon has higher frequencie, its actually the wave part of the light that has a higher frequency.
Albert Einstein proposed the photon theory of light, which suggests that light is made up of individual particles called photons. This theory helped explain the photoelectric effect and laid the foundation for the quantum theory of light. Einstein's work on light theory earned him the Nobel Prize in Physics in 1921.
