Unformatted text preview: t given by N = N exp − t / since the number of atoms is maintained to N = N hence the rate of decay of atoms from excited state to ground state is R = N /= 3.33x10 15 sec − 1 every atom emits one photon to decay to the ground state , therefore the number of photon emitted by atoms in the discharge tube is R = 3.33x10 15 / sec...
