Marks: +1, -0

The short wavelength limit for the Lyman series of the hydrogen spectrum is 913.4 Å. Calculate the short wavelength limit for Balmer series of the hydrogen spectrum.

Solution:

‌

=R(‌

n12

−‌

n22

)
∴ For Balmer Series: (λB)‌short ‌=4∕R
and For Lyman Series: (λL)‌short ‌=1∕R
∴λB=913.4×4Å=3653.6Å
