Why Distance Between Lines of Hydrogen Spectrum Decreases

[Ali Asadullah]

Why distances between lines of hydrogen spectrum decreases even though the distance between the shells of Hydrogen increases as we go to higher shells?

r=Ɛn2h2/πme

where
m=mass of electron,
e=charge on electron
h=planck's constant
n=principle quantum number
r=radius of hydrogen atom

This formula shows that the distance between the shells increases with the increase in Principle Quantum number.
Then why the distances between lines of hydrogen spectrum decreases?

Here's a picture showing the hydrogen spectrum:

Can you carefully explain the trend again using the picture as reference?

Whoops .. I think those labels are wrong! The H-atom spectra is the line spectrum on the bottom.

Yes, there's definitely something wrong with that figure!

Back to the OP - please post a link to the figure you are using and rewrite your question specifically in the context of the figure.
