Question
A photon of energy 10.2 eV corresponds to light of wavelength λ0. Due to an electron transition from n = 2 to n = 1 in a hydrogen atom, light of wavelength λ is emitted. If we take into account the recoil of the atom when the photon is emitted,
Options
A.λ = λ0
B.λ < λ0
C.λ > λ0
D.the data is not sufficient to reach a conclusion
Solution
Due to recoile of the H-atom, energy of photon must be less then 10.2eV, so its wavelength will be less than λ0.
