Albert Einstein in his 1905 paper on the photoelectric effect. Summarize as saying that when a photon strikes a metal it will cause electron flow. Wilhelm Hallwachs made the first photocells. An alloy of metals made the first photoresistors. Then solar cells.
Albert did not "invent" the effect, it was already known, but he EXPLAINED how it works.
Albert Einstein won a Nobel Prize for explaining the photoelectric effect.
Ultraviolet light best explains the interference phenomena. This type of light has a wave length shorter than visible light.
Einstein explained the photoelectric effect incorporating Planck's Quantum ideas. Einstein's explanation helped greatly to support Planck's Quantum Theory.

The Photoelectric Effect and the Compton effect, both of these effects are explained by Photons.
The photoelectric effect is a phenomena that can only be explained by the particle model.
The particle model explains compton scattering and the photo-electric effect perfectly, which the wave model utterly fails to do. The full spectrum of blackbody radiation can be easily derived with the particle model of light, but not with the wave model.
The ramp method best explains the particle model as far as buoyancy is concerned.
According to sir Isaac Newton, light is a stream of fast-moving particles. This was known as the particle model of light. There is a more simplified model when you study the behavior of light as light reflects off of mirrors and passes through lenses. This model is known as the ray model of light. Light is represented as a straight line or ray which shows the direction the light wave travels. Indeed!

At the simplest level it was the Bohr model.
The diagram is a model based on observations and experiments. Ecologists use models to explain phenomena and make predictions.
