Does wavelength of the incident rays play a role in the phenomenon of photoelectric effect?
Yes definitely. Reciprocal of wavelength is proportional to frequency
as lambda = v /frequency. v - the speed of the wave.
The frequency has to be greater than some minimum value known to be the threshold frequency. As frequency increases then kinetic energy of the photo electron also increases. If the frequency of the incident photon is less than the threshold and however higher the intensity, there is no chance of ejection of photo electron right from the surface of the substance. So no photo electric emission is possible.
What else can I help you with?
What is threshold wavelength?
Threshold wavelength refers to the minimum wavelength of light required to start a specific phenomenon, such as photoelectric effect or emission of electrons from a metal surface. Below this threshold wavelength, the desired effect does not occur.
Which phenomenon demonstrates a particle nature of light?
The photoelectric effect demonstrates the particle nature of light. In this phenomenon, light is shown to behave like a stream of particles (photons) by ejecting electrons from a material when it hits the surface.
What is the effect of wave nature of light on photoelectric effect?
The wave nature of light helps explain the phenomenon of interference observed in the photoelectric effect. When light waves interact with a material, interference can either enhance or diminish the ability of photons to eject electrons. This interference phenomenon is a key aspect of understanding the photoelectric effect.
Can the work function depend upon the wavelength of light?
Yes, definitely . For the given metal of particular work function, decrease in wavelength of the incident beam increases the maximum value of kinetic energy with which the photoelectrons are emitted, but the photoelectric current remains the same, stoppage voltage increases.
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.

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.
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.
Which phenomenon is inverse of photoelectric effect?
The inverse of the photoelectric effect is the Compton effect, where a photon interacts with an electron and loses energy in the process. This results in the photon scattering off the electron with a longer wavelength.
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.
Would a photon having a wavelength of 275 nm produce the photoelectric effect in lead?
Yes, a photon with a wavelength of 275 nm has enough energy (greater than the work function of lead) to eject an electron and produce the photoelectric effect in lead.
Which phenomenon shows the light interacts with matter as a particle of discrete quantity?
photoelectric effect
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.
