The wavelength of the radiation emitted when an electron falls from n = ∞ to n = 2 in a hydrogen atom is?
Q1. The wavelength of the radiation emitted when an electron falls from n = ∞ to n = 2 in a hydrogen atom is?
Answer: 364 nm
Explanation: Using Rydberg formula for n = ∞ to n = 2, wavelength is 364 nm; option B is for n = 4 to n = 2.
