Who discover photo electric effect and what date?
The photo electric effect was explained by Einstein in 1905 when he theorized that light could transfer its energy like a particle and knock electrons out of metals. But the actual effect had been observed by a number of scientists since 1887, they just couldn't come up with a satisfactory theory that explained everything they observed. I believe he got the Nobel Prize for his photo electric effect theory, although he is more famous for his Relativity theories.
What properties of light cannot be described by using the wave model of light?
Photo electric emisson or photo electric effect
What are photo-electrons?
An electron ejected from the surface of a material by the photoelectric effect
What characteristic of light did Einstein employ to explain the photo electric effect?
The particle nature of light
How do photons create electrons?
Photons create electrons in two senses. In the first sense, they don't really create electrons but eject them: from a surface in the photo-electric effect or from atoms or molecules in photo-ionization. Observing the photo-electric effect was a key part of discovering quantum mechanics. In the second sense, an electron is created together with its anti-particle, a positron, when the photon collides with another particle. Particle-antiparticle creation requires a lot more energy than "photo-ejection". This is conversion of energy into matter, in this case matter with a rest mass of just over a million electronvolts (in mass-equivalent units according to Einstein's E=mc^2). So the photon (and target particle) need to have kinetic energy of that amount for electron-positron pairs to be created.
Electrons ejected in the photoelectric effect are called?
Photo electrons. So current due to these photo electrons is named as photo electric current.
What is the ability of light to cause electron movement and electric current?
The photo-electric effect is the ability of light to cause the movement of electrons, which is called an electric current.

What properties of light cannot be described by using the wave model of light?
Photo electric emisson or photo electric effect
What are the proofs of the particles nature of light?
photo electric effect,compton's effect
What are the proofs of the particles of nature of light?
photo electric effect,compton's effect
What are photo-electrons?
An electron ejected from the surface of a material by the photoelectric effect
What is the reverse process of photoelectric effect?
reverse process of photo electric effect is done by the supply of electrons or heat to the metal that radiate certain radiation. among them the metals which emit visible radiation are normally used in house hold appliances

Albert Einstein got the Nobel Prize for his?
photo-electric effect, which is a very obvious manifestation
