In any circumstance where a threshold of energy is required to free an electron from a bound state, an incoming photon must have at least that energy to do the job. The energy of a photon is proportional to the frequency of the light, so the minimum energy corresponds to a minimum frequency of the light, or maximum wavelength necessary to free an electron. This observation was a major step in the development of radiation theory (Einstein).

What percents of xrays are produced in a photoelectric effect?
The amount of xrays produced in a photoelectric effect varies. . . . alot.
What does the slope of the graph of photoelectric current versus intensity signify in the photoelectric effect?
The current rises as does the intensity of light detected. The more light the greater the intensity, and the greater the current. The answer to the question is that photoelectric current displayed on a graph is shown as a slope that varies with the intensity of light. Someimes it can go up, sometimes it can go down.The ultimate answer is that the photoelectric effect is unreliable, but it is improving!
Is Reverse process of photoelectric effect is radioactivity?
No, nothing common, not even the 'opposite'
The emission of electrons from metal caused by light striking the metal is called?
Photoelectric effect.===================================== This phenomenon was discovered by Albert Einstein, for which he received the Nobel Prize for Physics. The solar cells that we use today is a direct application of the photoelectric effect, as the special metal absorbs Sun's photons and gives off electron (and the flow of electrons generates an electric current).
What device gives off electrons when light shines on a metal surface?
There is the photoelectric effect, which is the process that emitts electrons from a metals surface when light of a certain frequency shines on the surface. In the metal, the nuclei are surrounded by electrons, so when the incoming electrons strike the surface, they pull apart from the electrons of the metal because of how like charges detract from each other.
Which phenomenon demonstrates a particle nature of light?
The particle nature of light is illustrated by the photoelectric effect.
Match the experimental conditions applied to the photoelectric effect observed.?
conditions of photoelectric effect
What is the inverse process of photoelectric effect?
I think X-rays are the reverse process of photoelectric effect.
What percents of xrays are produced in a photoelectric effect?
The amount of xrays produced in a photoelectric effect varies. . . . alot.
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.
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.
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 does light produce in the photoelectric effect?
A candle
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!
