How does photoelectric effect work?
The photoelectric effect is when light strikes a material, causing electrons to be emitted. This occurs when the photons in the light have sufficient energy to overcome the binding energy of the electrons in the material. These energized electrons are then free to conduct electricity or participate in chemical reactions.
What is a byproduct of photoelectric absorption?
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.
Why photoelectric measurement are so sensitive to the nature of photoelectric surface?
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.
What is the difference between field emission and photoelectric emission?
* 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.

Does the photoelectric effect occur when light shines on metal?
Yes, the photoelectric effect occurs when light shines on metal. This phenomenon involves the emission of electrons from a material when it is exposed to light. The energy of the photons in the incident light must be sufficient to overcome the work function of the metal in order for electrons to be ejected.
What is meant by photoelectric colorimeter?
Photoelectric colorimeter is a medical term. Essentially, it is referring to a colorimeter using a photoelectric cell and appropriate filters instead of the eye.
Is there any importance in photoelectric effect?
One of the most revolutionary concepts in physics is the photoelectric effect. The photoelectric effect occurs when radiant energy is impinged on various metals and electrons are ejected from the metal surface. The ejected photoelectrons have a certain kinetic energy which can be measured by the produced voltage. Photoelectric current cannot be explained by the wave theory as diffraction and interference can, however. The photoelectric effect is important because it revealed some of the limitations of the classical wave theory and it gave closer insight into the nature of light- namely the quantization as photons.
Is photoelectric renewable or nonrenewable?
It is considered renewable. It photoelectric energy is created when the sun shines.
