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.
What Substances that conduct an electric current under certain conditions are most likely to be?
metalloids
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
What cell part allows only certain substances to difuse into and out of the cell?
The cell's membrane allows only certain substances to diffuse in and out of the cell.
What is electroluminescence?
A phenomenon that causes certain materials to glow (without getting hot) when electrically excited.
Is it true in he phenomenon known as the photoelectric effect electric current will flow when light shines on certain substances?
Yes true!
What is the phenomenon in which electrons are emitted from a metals surface when light of a certain frequency shines on it?
Photoelectric phenomenon
How a substances gets electric charge?
basically metals get charged by getting extra electrons or by missing them. baut certain substances get there charges by a physical phenomenon ,like friction ,heating,or any chemical reactions , it all results in electron transfers, and the substance get charged.
In the phenomenon known as the Doppler Effect electrons are ejected when light shines on certain substances?
The Doppler Effect is the change in the frequency of the sound you hear when a car sounding its horn passes you.When the electrons at the surface of an object absorb incident light sufficient for them to escape the surface this is known as the photoelectric effect.

Fort what topic did Albert Einstein win the Nobel prise for physics?
Albert Einstein won the Nobel Prize in Physics for his explanation of the photoelectric effect. The photoelectric effect is a phenomenon in which electrons can be emitted from a material when light of certain frequencies are shined onto the material.
What is non linear refraction?
The phenomenon whereby the refractive index of certain substances varies with light intensity
which event happens in a solar cell when the photoelectric effect occurs?
When you shine a certain level of light wavelength on metal, you can knock electrons off the atoms of the metal. This phenomenon was explained by Albert Einstein in 1905, for which he received a Nobel Prize in 1921.
