The wavelengths λ of spectral lines produced by the Hydrogen atom are given by the expression:
Calculate the Energy in eV required to ionise the atom
The Attempt at a Solution
n2 = 1 and n1 = infinity, therefore [tex]\lambda[/tex]=1/R.
E = p2/2m = h2/([tex]\lambda[/tex]^2*2Me)
Subbing in [tex]\lambda[/tex]=1/R. and rearranging gives:
E = (h2R2)/(2Me)
Why doesn't this give me the right answer?
