RafaIn the photoelectric effect, light transfers its energy to electrons in a material, causing them to be ejected from the material. This phenomenon demonstrates that light behaves as both a wave and a particle, known as photons. The energy of the photons must exceed the work function of the material for electrons to be emitted.

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 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.
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.
Do radio and microwaves produce photoelectric effect?
No, radio waves and microwaves do not produce the photoelectric effect. The photoelectric effect is the phenomenon where electrons are emitted from a material when it is exposed to light of sufficient frequency (typically ultraviolet or higher). Radio waves and microwaves have lower frequencies and energies than light, so they are not capable of causing the photoelectric effect.
What does not support the wave nature of light?
The photoelectric effect does not support the wave nature of light. This phenomenon can only be explained by the particle nature of light, as described by Albert Einstein in his theory of photons.
