The wavelengths and frequencies of photons in transition 1,2 and 3 for hydrogen like atom are lambda_(1),lambda_(2),lambda_(3), v_(1),v_(2) and v_(3) respectively. Then:

The wavelengths and frequencies of photons in transition 1,2 and 3 for hydrogen like atom are lambda_(1),lambda_(2),lambda_(3), v_(1),v_(2) and v_(3) respectively. Then:

In hydrogen atom, if lambda_(1),lambda_(2),lambda_(3) are shortest wavelengths in Lyman, Balmer and Paschen series respectively, then lambda_(1):lambda_(2):lambda_(3) equals

If tan 82(1)/(2^(@))=sqrt(lambda_(1))+sqrt(lambda_(2))+sqrt(lambda_(3))+2 then lambda_(1)+lambda_(2)+lambda_(3) is equal to
