In the photoelectric effect, electrons are ejected from a material when it is exposed to light of sufficient frequency. The energy of the incoming photons is transferred to the electrons, allowing them to overcome the binding energy of the material and escape. This phenomenon is used in devices like solar cells and photomultiplier tubes.
What else can I help you with?
How does the light intensity affect the photoelectric current?
Increasing light intensity results in more photons being incident on the photoelectric material, leading to more electrons being ejected, thus increasing the photoelectric current.
In the photoelectric effect what happens when lighthits the metal?
When light hits a metal in the photoelectric effect, it can transfer its energy to the electrons in the metal. If the energy of the light is high enough, it can cause the electrons to be ejected from the metal, creating a flow of electrical current.
Photoelectric affect what happens when light hits the metal?
When light hits a metal surface in the photoelectric effect, electrons are ejected from the metal if the light has sufficient energy (above the threshold frequency). This process demonstrates that light behaves as a particle (photons) with discrete energy levels when interacting with matter.

electrons are knocked off atoms causing electricity to flow

What happens to electrons if photon frequency is below threshold?
If the photon frequency is below the threshold frequency, the electrons do not have enough energy to be emitted from the material's surface, and no photoelectric effect occurs. The electrons will not be ejected and will remain bound to the material.
What happens to electrons in the photo electric effect?
Electrons are ejected from a metal surface when it is exposed to light of sufficient energy. This phenomenon is known as the photoelectric effect. The energy of the incident light is absorbed by the electrons, causing them to be emitted from the metal surface.
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.
Why X-rays are inverse of photoelectric effect?
X-rays and the photoelectric effect are related because X-rays are high-energy electromagnetic waves that can cause the photoelectric effect to occur in matter, where electrons are ejected from atoms when X-rays are absorbed. This happens because X-rays have enough energy to overcome the binding energy of the electrons in the atoms they interact with. So, in essence, X-rays can trigger the photoelectric effect in materials due to their high energy levels.
What happens to electrons in 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 does light produce in a photoelectric effect?
In the photoelectric effect, light produces electrons when it strikes a material surface. The energy of the incident light is transferred to the electrons, causing them to be ejected from the material.
How does the intensity of light affect the electrons emitted from a metal?
Increasing the intensity of light results in more photons hitting the metal surface, which can increase the number of electrons emitted through the photoelectric effect. This can lead to a higher current of ejected electrons being generated.
