Question

Second line of Balmer series is produced by which transition in spectrum of H-atom
1) 5 to 2
2) 5 to 1
3) 4 to 2
4) 4 to 1​

Answer 1

Second line of Balmer series is produced by which transition in spectrum of H-atom 4 to 2

Explanation:

Balmer series or Balmer lines is one of the set of six named series describing the spectral line emissions of the hydrogen atom.

Using Rydberg's Equation:

$\frac{1}{\lambda}=R_H\left(\frac{1}{n_i^2}-\frac{1}{n_f^2} \right )\times Z^2$

Where,

$\lambda$ = Wavelength of radiation

$R_H$ = Rydberg's Constant

$n_f$ = Higher energy level = ?

$n_i$ = Lower energy level = 2 (Balmer series)

Z= atomic number = 1 (for hydrogen)

The first line will have transition from 3 to 2 and thus the second line will have transition from 4 to 2.
