Whenever a hydrogen atom emits a photon in the Balmer series .

A hydrogen atom emits a photon corresponding to an electron transition from n = 5 to n = 1 . The recoil speed of hydrogen atom is almost (mass of proton ~~1.6 xx 10^(-27) kg) .

A hydrogen atom emits a photon corresponding to an electron transition from n = 5 to n = 1 . The recoil speed of hydrogen atom is almost (mass of proton ~~1.6 xx 10^(-27) kg) .

Assertion: In a hydrogen atom energy of emitted photon corresponding to transition from n = 2 to n = 1 is such greater as compared to transition from n=oo to n = 2 . Reason: Wavelength of photon is directly proportional to the energy of emitted photon.
