The Line Spectra of the Hydrogen Atom
PHXII12:ATOMS

356594 Assertion :
Between any two given energy levels, the number of absorption transitions is always less than the number of emission transitions.
Reason :
Absorption transitions start from the lowest energy level only and may end at any higher energy level. But emission transitions may start trom any higher energy level and end at any energy level below it.
