What lines of atomic hydrogen absorption spectrum fall withinthe wavelength range from `94.5` to `130.9nm`?

Explanation

These are the Lyman lines
` ħ omega=E_(H)((1)/(1)-(1)/(n^(2)))n= 2,3,4....`
For `n=2` we get `lambda=121.11nm`
For `n=3` we get `lambda=102.2nm`
For `n=4` we get `lambda=96.9 nm`
For `n=5` we get `lambda=94.64nm`
For `n=6` we get `lambda= 93.45nm`
Thus at the level of accuaracy of our calculation, there are four lines
`121.1nm, 102.2nm, 96.9nm` and `94.64nm`.
