Question

The different lines in the Lyman series have their wavelengths lying between :

Options

A.zero to infinit

B.900(A^o) to 1200 (A^o)

C.1000(A^o) to 1500 (A^o)

D.500(A^o) to 1000 (A^o)

Solution

for lyman series
shortest wavelength n = ∞ → n = 1
                     ᐃE = 13.6 eV
and Å
       Longest wavelength n = 2 → n = 1
                        ᐃE = 10.2 eV
       Å
