Frequency of light refers to the number of wave cycles that pass a specific point in a given time period. Higher frequency light waves have shorter wavelengths and carry more energy, while lower frequency light waves have longer wavelengths and less energy. This relationship is the basis for the spectrum of light, where different frequencies correspond to different colors.

What is the frequency in photoelectric effect?
In the photoelectric effect, the frequency of incident light determines the energy of the ejected electrons from a material. Electrons are only emitted from the material when the frequency of the incident light is greater than the threshold frequency, which is unique to each material.
What is the relationship between the kinetic energy of a photoelectron and the frequency of the incident light in the photoelectric effect?
In the photoelectric effect, the kinetic energy of a photoelectron is directly proportional to the frequency of the incident light. This means that higher frequency light will result in photoelectrons with greater kinetic energy.
What is the relationship between frequency and kinetic energy in photoelectric effect?
In the photoelectric effect, increasing the frequency of incident light increases the kinetic energy of the emitted electrons. This is because higher frequency light photons carry more energy, which can be transferred to the electrons during the photoelectric effect.
How does frequency affect light?
The frequency of light determines its color – higher frequency light appears bluer, while lower frequency light appears redder. In addition, the frequency of light affects its energy – higher frequency light carries more energy per photon. This is why higher frequency ultraviolet light is more harmful to living organisms than lower frequency visible light.
How does increasing the frequency of light in the photoelectric effect impact the emission of electrons?
Increasing the frequency of light in the photoelectric effect results in the emission of electrons with higher energy levels. This is because higher frequency light carries more energy, which allows electrons to be ejected from the material with greater kinetic energy.

If the frequency of light is greater than the threshold frequency will photoelectric effect starts?
Yes - that's how it works.

How does photoelectric effect take place below threshold frequency?
It doesn't, and that's the whole big mysterious fact about the photoelectric effect that was standing Physics on its ear about 100 years ago. It doesn't matter how bright the light is, there's no photoelectric effect if the light is below the threshold frequency. And if it's above the threshold frequency, it doesn't matter how dim the light is, those electrons come streaming off of the surface of the target.
In the Photoelectric effect after the threshold frequency what effect does the increased frequency have on the photocurrent If you assume the Intensity of the source to be constant?
The increased frequency increases the kinetic energy of the single electron ejected. Remember that the incident light releases a single electron when the threashod frequency is reached
In physics a change in frequency of light passing through a transparent medium?
RAMAN EFFECT
What is the emission of electrons from a metals surface when light of a certain frequency shines on it?
photoelectric effect
Which phenomenon can only be explained by assuming that light is quantized?
The photoelectric effect is a phenomenon that can only be explained by assuming that light is quantized. In this effect, electrons are ejected from a material when it is exposed to light of a certain frequency. The energy of the ejected electrons is dependent on the frequency of the light, supporting the idea that light is made up of discrete packets of energy called photons.
What is threshold frequency in photoelectric effect?
Threshold frequency refers to the minimum frequency of incident light required to eject electrons from the surface of a metal in the photoelectric effect. Electrons will only be emitted if the frequency of light is equal to or greater than the threshold frequency, as lower frequencies do not possess sufficient energy to overcome the work function of the metal.
