What happens to the energy of emitted electrons when the frequency of incident light in the photoelectric effect is increased?

In the photoelectric effect, the energy of the emitted electrons is directly related to the frequency of the incident light. When the frequency of the light increases, it provides more energy to the electrons that are released from the material. According to the equation derived from the photoelectric effect principles, the energy of the emitted electrons is given by ( E = hf - \phi ), where ( E ) is the kinetic energy of the emitted electrons, ( h ) is Planck's constant, ( f ) is the frequency of the incident light, and ( \phi ) is the work function (the minimum energy needed to release an electron from the material).

As the frequency ( f ) increases, the energy ( hf ) increases as well, resulting in an increase in the kinetic energy of the emitted electrons. This means that electrons emitted under higher frequency light will have higher energy compared to those emitted by lower frequency light. Thus, increasing the frequency of the incident light leads to an increase in the energy of the emitted electrons. This relationship is a fundamental concept of the photoelectric effect and highlights the particle nature of light.
