In the phenomenon known as the Doppler Effect electrons are ejected when light shines on the 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.

Is it true that in phenomenon known as the Doppler effect electric current will flow when light shines on certain substances?
It is not true that the Doppler effect has anything to do with electricity and the flow of current. The Doppler effect involves pitch and sound frequency of moving objects, for example the apparent noise changes of an approaching car.
What is the phenomenon in which electrons are emitted from a metals surface when light of a certain frequency shines on it?
Photoelectric phenomenon
What occurs when light causes electrons to move when it hits some substances?
When light hits certain substances, the energy from the light can be absorbed by electrons in the material, causing them to become excited and move to a higher energy level. This movement of electrons generates an electrical current, a phenomenon known as the photoelectric effect.
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.
What is non linear refraction?
The phenomenon whereby the refractive index of certain substances varies with light intensity
Is it true in the phenomenon known as the photoelectric effect electric current will flow when light shines on certain substances?
Yes, in the photoelectric effect, when light shines on certain substances, electrons are ejected from the material, creating an electric current. This effect occurs when photons (light particles) transfer enough energy to electrons in the material to overcome the binding energy holding them in place.
Is it true in he phenomenon known as the photoelectric effect electric current will flow when light shines on certain substances?
Yes, in the photoelectric effect, electric current is produced when light shines on certain substances known as photosensitive materials. This occurs when photons (particles of light) strike the material's surface and transfer their energy to electrons, causing them to be ejected and generate an electric current.
What is it called when light hits a certain metal and causes electrons in a metal to move?
The phenomenon is called the photoelectric effect, where light hitting a metal surface causes the ejection of electrons from the metal.
What happens to electrons in the photoelectric effect?
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.
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.
