The wavelengths involved in the spectrum of deutrium ("_1H^2) are slightly different from that of hydrogen spectrum, because:
The hydrogen atom in the ground state is excited by mass of monochromatic radiations of wavelength lambda Å . The resulting spectrum consists of maximum 15 different lines . What is the value of lambda ? ( R_H = 109737 cm^(-1)) .
