When a hydrogen atom emits a photon in going from n=5 to n=1, its recoil speed is almost

The recoil speed of a hydrogen atom after it emits a photon in going from n=5 , state to n=1 state is (in ms^(-1) )

The recoil speed of a hydrogen atom after it emits a photon is going form n=5 state to n =1 state is ….. m/s.

Whenever a hydrogen atom emits a photon in the Balmer series

The recoil speed of hydrogen atom after it emits a photon in going from n = 2 state to n = 1 state is nearly [Take R_(oo) = 1.1 xx 10^(7) m and h = 6.63 xx 10^(-34) J s]
