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.
What else can I help you with?
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.
In the photoelectric what happens when light hits the metal?
electrons are knocked off atoms causing electricity to flow
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.
Does the photoelectric effect occur when light shines on metal?
Yes, the photoelectric effect occurs when light shines on metal. This phenomenon involves the emission of electrons from a material when it is exposed to light. The energy of the photons in the incident light must be sufficient to overcome the work function of the metal in order for electrons to be ejected.
When light is incident on a metal surface it emits electrons What happens if the intensity of light increases?
If the intensity of light increases, more photons will be incident on the metal surface, leading to a higher rate of electron emission through the photoelectric effect. This results in a higher current of emitted electrons.

Will indium display the photoelectric effect with UV light?
Yes, indium can display the photoelectric effect when exposed to UV light. When UV light shines on a metal surface like indium, electrons are ejected from the surface due to the photon energy exceeding the work function of the metal. This phenomenon is known as the photoelectric effect.
When light is incident on a metal surface it emits electrons What happens if the intensity of light increases?
If the intensity of light increases, more photons will be incident on the metal surface, leading to a higher rate of electron emission through the photoelectric effect. This results in a higher current of emitted electrons.
Can photoelectric effect be observed for all metals under same condition of incident light?
no , it cannot be observed in same conditions of incident light because, the threshold energy will be different for different metals.so in that particular threshold energy only the photoelectric effect for that metal can be observed.....
What did photoelectric experimenting demonstrate?
Light can cause electrons to be released from the surface of a metal. <<<<Apex>>>>
What device is known when electrons are emitted when light shines on a metal surface?
The device you are referring to is a photoelectric cell or a photodiode. When light shines on the metal surface of these devices, electrons are emitted in a process called the photoelectric effect, which generates an electric current.
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.
What does light produce in the photoelectric effect?
Light produces electrons in the photoelectric effect. When light of sufficient energy (photon energy) shines on a metal surface, it can eject electrons from the surface, creating a flow of current.
What is the result of visible light being absorbed by a metal?
When visible light is absorbed by a metal, it can cause the metal to heat up or emit electrons in a process called the photoelectric effect.
