If λ = c 2 n 2 n 2 - 2 2 for Balmer series, what is the value of c 2 ?

Options

  1. A4 R H
  2. B2 R H
  3. C2 R H
  4. D4 R H

Correct answer

A. 4 R H

Step-by-step solution

λ = c 2 n 2 n 2 - 2 2 or 1 λ = 1 c 2 n 2 - 2 2 n 2 = 1 c 2 1 - 2 2 n 2 = 2 2 c 2 1 2 2 - 1 n 2 So, R H = 2 2 c 2 or c 2 = 4 R H
