When an electron makes transition from higher energy level having energy E2(n2) to a lower energy level having energy E1 (n1) then a photon of frequency v is emitted.
RUTHERFORD'S ATOMIC MODEL:- Rutherford proposed that all the positive charge and mass of the atom was concentrated in a small central region which is called the nucleus.This mo
calculate the frequency of radiation which must be incident on a substance placed in magnetic field strength so that the electron can absorb energy
Frequency:- The number of vibration done per second by an oscillation body is known its frequency. It is denoted by V. The S.I unit is Hz.
