Photoelectric Effect is the emission of electrons by substances, especially metals, when electromagnetic radiations such as x-rays or visible light, of certain minimum frequency, fall on their surfaces. If the energy (from EM Radiations) absorbed is more than the ionization energy then electrons will be emmitted. The emitted electrons can be referred to as photoelectrons in this context.
The effect was discovered by H. R. Hertz in 1887. The effect is also termed the Hertz Effect
Fluorescence is a luminescence that is mostly found as an optical phenomenon in cold bodies, in which the molecular absorption of a photon triggers the emission of another photon with a longer wavelength. The energy difference between the absorbed and emitted photons ends up as molecular vibrations or heat. Usually the absorbed photon is in the ultraviolet range, and the emitted light is in the visible range, but this depends on the absorbance curve and Stokes shift of the particular fluorophore. Fluorescence is named after the mineral fluorite, composed of calcium fluoride, which often exhibits this phenomenon.

Which phenomenon demonstrates a particle nature of light?
The particle nature of light is illustrated by the photoelectric effect.
What is the inverse process of photoelectric effect?
I think X-rays are the reverse process of photoelectric effect.
What does light produce in a photoelectric effect?
When the light combine with the speed in a photoelectric effect it produces a picture of the object.
Who won the Nobel Prize for explaining the photoelectric effect?
Explaining the photoelectric effect wonEinstein a Nobel Prize in 1921.
What is Einstein photoelectric effect?
Einstein's photoelectric effect work found that the incident light involved in the photoelectric effect was made of individual quanta (photons) that interacted with the metal's electrons like discrete particles, not waves.

What percents of xrays are produced in a photoelectric effect?
The amount of xrays produced in a photoelectric effect varies. . . . alot.
Can photoelectric effect done in vaccum?
Certainly, of course, and you betcha. The presence of air has no function or involvement in the photoelectric effect.

What is photoelectric effect?
The photoelectric effect is a phenomenom that occurs when you fire a photon with high enough energy aggainst matter, and it expells an electron after absorbing the photon's energy.
When was Photoelectric effect found?
1897 by Heinrich Hertz
When was the photodiode invented?
When Einstein discovered photoelectric effect!
