ViviAlbert Einstein explained the photoelectric effect by proposing that light consists of particles called photons. He theorized that when light shines on a metal surface, photons transfer their energy to electrons in the metal, causing them to be emitted as electric current. This understanding revolutionized the field of quantum physics.
According to the classical explanation of the photoelectric effect, if a photon of an appropriate wavelength and frequency strikes metal atoms, electrons are ejected.
When an electron absorbs the energy of the incident electromagnetic wave, it has more energy than normally and it jumps to a higher energy state. If it has enough energy it breaks off. If it doesn't, the energy is re-emmited.
Generally, Fermi's Golden Rule is used to calculate the probability of jumping from one energy state to another.
The modern explanation differs from the traditional in because it treats light as waves rather than particles.

What was Albert Einstein's contribution to our understanding of photoelectric effect?
He was the first one to successfully explain this effect, and thus created the basic form of what became modern Quantum Mechanics (a theory that in its final form he rejected because it is probabilistic not deterministic).Note: Einstein did not receive his Nobel Prize for Relativity, but for his work on Brownian Motion and the Photoelectric Effect.
Albert Einstein ever win a nobel prize?
Yes, Albert Einstein was awarded the Nobel Prize in Physics in 1921 for his discovery of the photoelectric effect, which helped establish the theory of quantum mechanics.
What is light quantum hypothesis?
The light quantum hypothesis, proposed by Albert Einstein in 1905, suggests that light is made up of discrete packets of energy called photons. This hypothesis helped to explain the photoelectric effect and laid the foundation for the development of quantum mechanics.
Who won the Nobel Prize for physics in 1921?
Albert Einstein won the Nobel Prize for Physics in 1921 for his work on the photoelectric effect, which formed the basis of quantum theory.
What prize did Einstein win in 1921?
Einstein won the Nobel Prize in Physics in 1921 for his services to theoretical physics and his discovery of the photoelectric effect.
