The wavelengths involved in the spectrum of deuterium (1D2) are slightly different from that of hydrogen spectrum, because
- size of the two nuclei are different
- masses of the two nuclei are different
- nuclear forces are different in the two cases
- attraction between the electrons and the nucleus is different in two cases
Answer
(B) masses of the two nuclei are different
