Question

a beam of monoenergetic photons of energy 9 eV is incident on a hydrogen gas containing all atoms in ground state it is found that the beam is fully transmitted without absorption why​

Answer 1

Answer:

It is because ot requires atleast 10.2ev energy for electrons to go from n1 to n2 shell .

Explanation:

energy of n1 : -13.6ev

enegry of n2 : -3.4ev

so minimum required energy is -3.4-(-13.6)ev
