FREE Expert Solution

We are asked which transition in a hydrogen atom would absorb the photon of greatest frequency


The larger the wavelength the smaller the frequency. 


We’re going to use the Balmer Equation which relates wavelengths to a photon’s electronic transitions.

1λ=RZ21n2final-1n2initial

λ = wavelength, m
R = Rydberg constant = 1.097x107 m-1 
Z = atomic number of the element
ninitial = initial energy level
nfinal = final energy level


Absorbing energy means we go from lower to a higher level.
