Frequency of the series limit of Balmer series of hydrogen atom in terms of Rydberg's constant (R) and velocity of light (c) is

Options

  1. A4 Rc
  2. B4 Rc
  3. CRc
  4. DRc 4

Correct answer

D. Rc 4

Step-by-step solution

Wavelength of Balmer series is given as, 1 = R ( 1 n ₁^2 - 1 n ₂^2 ) where n ₁=2 For series limit, n ₂= 1 = R ( 1 4 - 1 )= R ( 1 4 ) Now, v= c v= R c 4
