Question

Use the Rydberg equation to calculate the frequency of a photon absorbed when the hydrogen atom undergoes a transition from n

Answer 1

Answer #1

From Rhydberg equation,

Wavenumber = 1.09677×107 [1/n1 2 - 1/n 22]

= 1.09677×107[1/22 - 1/42]

= 1.09677×107 [1/4 - 1/16]

= 1.09677×107×3/16

= 2.056×106 m-1

Frequency = wavenumber×speed of light

= 2.056×3×106×108

= 6.17×1014 s-1
