Question

A hydrogen atom emits a photon corresponding to an electron transition from n = 5 to n = 1 . If R is the Rydberg constant, then the wavelength of emitted photon is, 25 24 R, 24 R 25, 4 5 R, 5 R 4

MARKS App · Accepted Answer

From Rydberg's equation, wavelength is related to transition is given by, 1 λ = R 1 n f 2 - 1 n i 2 ⇒ 1 λ = R 1 1 2 - 1 5 2 ⇒ 1 λ = R 25 - 1 25 ⇒ 1 λ = 24 R 25 ⇒ λ = 25 24 R
