A photoelectron is an electron emitted from a material when it absorbs energy from light, typically ultraviolet or X-ray radiation. This process is known as the photoelectric effect and is used in various scientific techniques such as photoelectron spectroscopy to analyze the electronic structure of materials.

What is an ejected electron called?
An ejected electron is called a photoelectron.
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.
How do you calculate kinetic energy of the photoelectron emitted from the surface?
To calculate the kinetic energy of a photoelectron emitted from a surface, you can use the equation: ( KE = hf - \phi ), where ( KE ) is the kinetic energy of the photoelectron, ( h ) is the Planck constant, ( f ) is the frequency of the incident photon, and ( \phi ) is the work function of the material.
Light with an energy equal to three times the work function of a given metal causes the metal to eject photoelectrons. What is the ratio of the maximum photoelectron kinetic energy to the work functio?
The maximum photoelectron kinetic energy is given by the equation: Energy of incident light - Work function. If the energy of the incident light is three times the work function, then the maximum kinetic energy of the photoelectrons will be three times the work function. Therefore, the ratio of the maximum photoelectron kinetic energy to the work function is 3:1.
What is the time lag between the arrival of light at a metal surface and the emission of photoelectron?
The time lag between the arrival of light at a metal surface and the emission of a photoelectron is extremely short, typically on the order of a few femtoseconds (10^-15 seconds) to tens of femtoseconds. This process is known as the photoelectric effect, where electrons are emitted from a material when it absorbs photons with sufficient energy to overcome the material's work function.

What is photo electron spectroscopy?
The utilization of photo-ionization and kinetic energy distribution analysis of emitted photoelectrons to study the electronic state and composition of the surface region of a sample is known as photoelectron spectroscopy. This technique can be subdivided into two areas: X-ray photoelectron Spectroscopy and Ultraviolet Photoelectron Spectroscopy.
