When a hydrogen atom is excited from ground state to first excited state then

When a hydrogen atom is excited from ground state to first excited state then

The de-Brogile wavelength associated with electron in the n = 4 level is :-

Nomination of electron is 5200 A .At which velocity of electron its wavelength is equal to photon.

An electron collides with a fixed hydrogen atom in its ground state. Hydrogen atom gets excited and the colliding electron loses all its kinetic energy. Consequently the hydrogen atom may emits a photon corresponding to the largest wavelength of the Balmer series. The K.E. of colliding electron will be..
