Flashcards in Definitions Deck (6):
It is the release of electrons from the surface of a metal when electromagnetic radiation is incident on it's surface
It is the minimum frequency of an e.m radiation required for a photon to eject an electron from the surface
1- When does photoemission takes place ?
2- What can you say about threshold frequency of metals
1-It takes place instantaneously , there is no decay between illumination and emission
2-Different metals have different threshold frequency
-What about emission? Talk about frequency and intensity
-Emission or not it only depends on the frequency of radiation.
-It does not depend not then intensity of radiation
For a given frequency...
The rate of emission of photoelectrons is proportional to the intensity of radiation
