Tips and Tricks on Dual Nature Of Matter And Radiation


 


1
Define work function of a metal?
The minimum energy required for an electron to escape from the metal surface is called the work function of the metal



2
Define 1eV
1eV is the energy gained by an electron when it is accelerated through a potential difference of one volt.



   3
How photo electric current depends on intensity of incident light?
Above threshold frequency, photoelectric current is directly proportional to intensity of incident light.
