Tips and Tricks on Dual Nature Of Matter And Radiation


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

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