The wavelengths involved in the spectrum...

The wavelengths involved in the spectrum of deuterium `(._(1)^(2)D)` 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

Text Solution

Verified by Experts

The correct Answer is:
C
The wavelength involved in the spectrum of deuterium `(._(1)^(2)D)` are slightly different from that of hydrogen spectrum because masses of two nuclei are different.
