Consider three electron jumps described below for the hydrogen atom
`{:["X: n=3 to n=1"],["Y: n=4 to n=2"],["Z: n=5 to n=3"]:}`
(a) The photon emitted in which transition ` X, Y` or (Z) will have shortest wavelength ?
(b) For which transition will the electron experience the longest charge in orbit radius ?

Answer

`'x'`

Explanation

`{:(x:,,n=3,"to",,n=1,(12.09 eV)),(y:,,n=4,"to",,n=2,(2.55 eV)),(z:,,n=5,"to",,n=3,(0.967 eV)):}`
Shortest wavelength `rArr` maximum energy `rArr n=3 "to" n=1 (12.09 eV)`
