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.
What else can I help you with?
What is the wave model of light?
The wave model of light proposes that light waves travel through space as electromagnetic waves, characterized by their frequency and wavelength. It explains phenomena like interference, diffraction, and polarization, supporting the idea that light behaves as a wave.
What does the particle model explains of light?
The particle model of light explains that light behaves like a stream of particles called photons. It helps account for phenomena such as the photoelectric effect and the discrete nature of light energy.
The particle model of light explains how light can?
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.
What describes light travelling as wave?
a wave model of light.
Compare wave and particle models of light. What phenomena can only be explained by the particle model?
The wave model of light describes light as an electromagnetic wave that exhibits properties like interference and diffraction. The particle model of light, on the other hand, describes light as a stream of particles called photons. Phenomena like the photoelectric effect and Compton scattering can only be explained by the particle model of light, where light behaves as discrete particles (photons) interacting with matter.

Phenomena such as diffraction and interference can be most easily explained in terms of what?
Phenomena like diffraction and interference can be most easily explained using the wave nature of light. These phenomena occur when light waves interact with each other or with obstacles in their path, leading to the observed patterns of light and dark fringes. The behavior of light as a wave can explain the way it diffracts around obstacles and interferes constructively or destructively to produce interference patterns.

Phenomena like the photoelectric effect and Compton scattering can only be explained by the particle model of light, where light behaves as discrete particles (photons) interacting with matter.
The wave model of light does not explain?
The wave model of light does not explain certain behaviors of light, such as the photoelectric effect, where light behaves as discrete particles (photons) instead of a continuous wave. This discrepancy led to the development of the dual nature of light, which incorporates both wave and particle properties to fully describe its behavior.
What behavior of light is evidence for a wave model light?
Interference, diffraction.
What behavior of light is evidence for wave model of light?
Interference, diffraction.
Which model of light states that light travels in a series of waves?
The wave theory of light is the idea, supported by a number of scientists over the years, that light behaves as waves. It has been superseded by Quantum theory, which says (in part) that light sometimes behaves like a particle and sometimes like a wave.
What model explains the behavior of light when light passes through the polarizing filter?
miss america
Which model of light states that light is composed of millions of particals?
The particle model of light, also known as the photon model, describes light as composed of individual particles called photons. These photons have energy and momentum, and collectively give rise to the properties of light such as reflection, refraction, and interference.
