The ratio of minimum wavelengths of Lyman and Balmer series will be

Options

(a) 5
(b) 10
(c) 1.25
(d) 0.25

Correct Answer:

0.25

Explanation:

Minimum wavelength is for higher energy n = 1 → n = ∞, energy = E₀.

n = 2 → n = ∞, energy = E₀/4.

.·. Balmer line has 4 times the wavelength.

.·. Ratio of minimum wavelength is (1/4) = 0.25
