In order for an electron to be ejected from a metal surface, the electron must be struck by a photon with at least the minimum energy needed to knock the electron loose.

What is the difference between particle and wave theory of light?
Particle theory of light can explain Photoelectric Effect,Compton effect,Pair production.... wave theory of light can explain interference,refraction...
Is Compton effect support the wave theory of light or particle theory?
yes it supports the wave theory of light...
What did photoelectric effect prove?
The photoelectric effect proves that light is composed of quanta called photons (packets of enegy) and therefore proves the Photon Theory composed by Einstein.
What is the particle model of light?
The particle model of light entails that light consists of tiny packages of energy called photons. Because light is an electromagnetic wave the model is a part of the general model for electromagnetism. This model is called Quantum Electrodynamics, or QED in short.
Is there any importance in photoelectric effect?
One of the most revolutionary concepts in physics is the photoelectric effect. The photoelectric effect occurs when radiant energy is impinged on various metals and electrons are ejected from the metal surface. The ejected photoelectrons have a certain kinetic energy which can be measured by the produced voltage. Photoelectric current cannot be explained by the wave theory as diffraction and interference can, however. The photoelectric effect is important because it revealed some of the limitations of the classical wave theory and it gave closer insight into the nature of light- namely the quantization as photons.

Who developed the theory of photons being quantized?
Einstein, and he used the theory to describe the photoelectric effect.
What two experiments involving light and matter could not be explained by the wave theory of light?
In the days before quantum mechanics there was discussion whether light was a particle or wave. The problem was that neither one could explain all phenomena completely. For example, the particle theory couldn't not account for interference patterns that can be made with light, but the wave theory could not account for the photo-electric effect. In this effect a photon (a light particle) deposits energy into a metal causing the metal to eject an electron. The puzzling thing was that increasing the intensity of the light did not increase the kinetic energy of the ejected electrons, only the amount of such ejected electrons. The photo-electric effect was finally tackled by Albert Einstein (for which he won the Nobel Prize in 1921), and light is now regarded as consisting of 'wave-packets' with photons have a unintuitive wave-particle duality.

Explain how photoelectric effect confirms particle nature of radation?
The photoelectric effect is a quantum electronic phenomenon in which electrons are emitted from matter after the absorption of energy from electromagnetic radiation such as x-rays or visible light.
Did albert Einstein invent anything that means something to the world?
Besides discovering the photoelectric effect, Einstein developed the Theory of Special Relativity and the Theory of General Relativity, which are the basis for quantum theory and particle theory, and the formula E=Mc2 that indirectly led to the atomic bomb, nuclear power, and much of the current theory about the structure of the universe. Other than that, not much.
How is Planck's quantum theory related to the photoelectric effect?
E=hf where f is frequency and h is plank's constant.
What are two Albert Einstein's important contributions?
The photoelectric effect, for which he won his Nobel Prize, and the Theory of General Relativity.
