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
