One byproduct of photoelectric absorption is the ejection of an electron from an atom. This process occurs when a photon's energy is entirely absorbed by an atom, causing an electron to be released from its orbit around the nucleus. This electron can go on to contribute to electrical conductivity or ionization processes.
No, photoelectric absorption decreases with increasing photon energy (kVp). This is because higher-energy photons are more likely to be transmitted through the material or undergo Compton scattering rather than being absorbed through the photoelectric effect.
Compton scattering involves the collision of a photon with an electron, resulting in the photon losing energy and changing direction. The photoelectric effect, on the other hand, involves the absorption of a photon by an electron, causing the electron to be ejected from the material. In summary, Compton scattering involves the photon changing direction and losing energy, while the photoelectric effect involves the absorption of the photon by an electron.
* emisssion of electron from the surface of the metal when light of suitable frequency falls-photoelectric emission. * emision of electron from the metal by quantum tunnling of electron.
Photoelectric measurements are sensitive to the nature of the photoelectric surface because the surface properties, like work function and reflectivity, directly affect the efficiency of electron emission when photons are absorbed. The surface characteristics influence the energy required for electron liberation, impacting the overall photoelectric effect.
Yes, the thickness of lead does have an effect on the absorption of gamma rays. A thicker layer of lead will be more effective at absorbing gamma rays compared to a thinner layer. This is because gamma rays interact with matter through processes like photoelectric absorption and Compton scattering, which are more likely to occur with a greater thickness of lead material.

The removal of one or more electrons from an atom or molecule by absorption of a photon of visible or ultraviolet light. (Also known as atomic photoelectric effect.)
No, the photoelectric effect is the emission of electrons from a material due to the absorption of photons. Infrared rays have lower energy photons than visible light, so they are not typically energetic enough to cause the photoelectric effect. Only photons with enough energy, such as ultraviolet or higher energy photons, can induce the photoelectric effect.

Ionization is the process of removing an electron from an atom or molecule, creating an ion. This process can occur through collisions with high-energy particles. On the other hand, the photoelectric effect involves the ejection of an electron from a material when it absorbs a photon of sufficient energy. In terms of their interaction with matter, ionization can occur through various mechanisms, while the photoelectric effect specifically involves the absorption of photons to release electrons.

Photoelectric colorimeter is a medical term. Essentially, it is referring to a colorimeter using a photoelectric cell and appropriate filters instead of the eye.
