wave-particle duality
a+
Einstein first proposed the idea of photons as discrete packets of light energy to explain the photoelectric effect. According to his hypothesis, light is composed of individual particles called photons that transfer their energy to electrons upon striking a material surface. Additionally, Einstein's explanation of the double-slit experiments involved the concept of wave-particle duality, stating that light exhibits both wave-like and particle-like properties.
Einstein used the equation E = hf to explain the photoelectric effect, where E is the energy of a photon, h is Planck's constant, and f is the frequency of the light. This equation shows that the energy of a photon is directly proportional to its frequency.
Albert Einstein applied the concept of a quantum to explain the photoelectric effect in his 1905 paper. He proposed that light consists of discrete packets of energy called photons, which interact with electrons in materials to release them from the surface.
Apex Light is made of photons.
Einstein did few experiments. He was what is known as a "theoretical" physicist. These are people who work chiefly with equations on pen and paper (or nowadays a computer). Other physicists are known as "experimental" physicists who work with equipment and design experiments to solve problems. The skills for each are different enough that few physicists do both well.

Einstein's two papers explained the theory of special relativity and the photoelectric effect. The paper on special relativity introduced the concept of space-time and the relationship between space and time, while the paper on the photoelectric effect explained how light behaves as both a wave and a particle.
Einstein was inspired by the fact that increasing the intensity of light did not increase the kinetic energy of ejected electrons in the photoelectric effect. This inconsistency with classical wave theory helped him propose that light consisted of discrete packets of energy called photons.
Einstein employed the particle-like nature of light, known as photons, to explain the photoelectric effect. He proposed that light is made up of discrete packets of energy (photons) that can transfer their energy to electrons in a material, causing them to be emitted. This idea helped to explain why the photoelectric effect occurred instantaneously at certain frequencies of light, as the energy of individual photons is proportional to their frequency.
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 developed the theory of the photoelectric effect while working as a patent examiner in Bern, Switzerland in 1905. He proposed that light could be understood as consisting of particles called photons that interact with matter. This theory helped to explain certain behaviors of light that could not be explained by classical physics.
