PhysicsNEET 2024Hydrogen spectrum and energy levels

Atoms

Match List I with List II.

List I (Spectral lines of hydrogen for transitions from)List II (Wavelength, nm)
A. to I. 410.2
B. to II. 434.1
C. to III. 656.3
D. to IV. 486.1

Choose the correct answer from the options given below:

  1. A.A-III, B-IV, C-II, D-I✓
  2. B.A-IV, B-III, C-I, D-II
  3. C.A-I, B-II, C-III, D-IV
  4. D.A-II, B-I, C-IV, D-III

Solution

Balmer wavelengths follow : the smallest jump () gives the longest wavelength, 656.3 nm , then 486.1, 434.1 and 410.2 nm as rises. Hence A-III, B-IV, C-II, D-I.
