Question

Problem 2.10
What are the frequency and wavelength
of a photon emitted during a transition
from n= 5 state to the n= 2 state in the
hydrogen atom?​

Answer 1

Explanation:

=R[n121−n221]

λ1=109677.6 cm−1×[221−521]

λ1=23032.3 cm−1

λ=4.34×10−5 cm

Convert unit from cm to nm

1 cm =107 nm

λ=4.34×10−5 cm×1 cm107 nm

λ=434 nm
