Question

The wavelengths involved in the spectrum of deuterium text(12 textD text) are slightly different from that of hydrogen spectrum, because- (A) Sizes of the two nuclei are different (B) Nuclear forces are different in the two cases (C) Masses of the two nuclei are different (D) Attraction between the electron and the nucleus is different in the two cases

Wavelength involved in the spectrum also depends on mass of nuclei apart from nuclear charge.

Q. The wavelengths involved in the spectrum of deuterium (12​D) are slightly different from that of hydrogen spectrum, because-

Sizes of the two nuclei are different

Nuclear forces are different in the two cases

Masses of the two nuclei are different

Attraction between the electron and the nucleus is different in the two cases

Wavelength involved in the spectrum also depends on mass of nuclei apart from nuclear charge.

Q. The wavelengths involved in the spectrum of deuterium $(_{1}^{2} D)$ are slightly different from that of hydrogen spectrum, because-
