I have an odd problem here. I need to show that:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]KE = \frac{{\frac{{\Delta \lambda }}{\lambda }}}{{1 + (\frac{{\Delta \lambda }}{\lambda })}}hf[/tex]

I've basically derived [tex] KE = \frac{{hc}}{{\lambda _o }} - \frac{{hc}}{{\lambda '}}[/tex] down to…

[tex] KE(\frac{{\lambda '}}{{\lambda _o ^2 }}) = (\frac{{\Delta \lambda }}{{\lambda _o }})hf[/tex]

but I'm not sure how I can turn that [tex] \frac{{\lambda '}}{{\lambda _o ^2 }}[/tex] into a [tex] 1 + (\frac{{\Delta \lambda }}{{\lambda _o }})[/tex]

Can anyone help?
