Question

what will be increase in radius when electron of hydrogen atom jumps from r2 to r1?​

Answer 1

E2 =

$\frac{ {- ke}^{2}}{{2r1} }$

E1 =

$\frac{ {- ke}^{2}}{{2r2} }$

DE = E2 - E1 =

$\frac{ {ke}^{2}}{{2} }$

$(\frac{1}{r1} - \frac{1}{r2} )$

=

\frac{ke(r2-r1)}{2r1r2} = \frac{hc}{λ}

λ =

$\frac{2ch \: r1r2 }{ke ^{2}(r2 - r) }$

hope this will help you ⚜
