Consider a hydrogen like atom whose energy in 
th excited state is given by 
, when this excited atom makes a transition from excited state to ground state, most energetic photons have energy 
and least energetic photons have energy 
. The atomic number of atom is
Text Solution
Verified by ExpertsThe correct answer is:
A
Maximum energy is liberated for transition 
and minimum energy for 
.
Hence, 
……… (i)
and 
……… (ii)
Solving Eqs. (i) and (ii), we get
