When the arrival of a beam of light at a surface?
when arrival of a beam of light at a surface
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.
The arrival of a light beam at a surface?
Whats the question?
What is threshold wavelength?
The greatest wavelength of radiation for a specified surface for the emission of electrons.
How do you calculate kinetic energy of the photoelectron emitted from the surface?
First, you need to work out the energy produced ie. E=hc/ lambda then you subtract its work function from the energy produced ie. KE=E-Eo
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.

What are the differences between thermionic emission and evaporation?
Thermionic emission occurs when electron leaves the surface of metals while evaporation occur in liquid when strong electron gain energy and escape the liquid surface in gaseous form
What is an electron emission?
The process in which an electron emit from metal surface into surrounding is known as electrons emission
What happens to the distance in arrival times between P waves and S waves as the distance for the earthquake increases?
surface waves
Which statement best describes the light that will cause emission of electrons from a given metal through the photoelectric effect?
This is an interaction between photons and the surface of the metal.

What is the emission of electrons from a metals surface when light of a certain frequency shines on it?
photoelectric effect
How do you calculate kinetic energy of the photoelectron emitted from the surface?
First, you need to work out the energy produced ie. E=hc/ lambda then you subtract its work function from the energy produced ie. KE=E-Eo
What is the emission of electrons from a metals surface?
the external energy given to electrons,thier kinetic energy increases.thus electrons move from metal surface
