The ratio of maximum to minimum wavelength in Balmer series hydrogen atom is

The ratio of maximum to minimum wavelength in Balmer series hydrogen atom is
  1. 36:5
  2. 3:4
  3. 9:5
  4. 5:9

Solution

Maximum wavelength of Balmer series is given by Minimum wavelength, Dividing Eq. (2) by Eq. (1) $\frac{\lambda}{\lambda^{\prime}}=\frac{9}{5}$
