Electrons in a hydrogen-like atom (Z = 3a) make transitions from the fourth excited state to the third excited state and from the third excited state to the second excited state. The resulting radiations are incident on a metal plate

A moving hydrogen atom makes a head-on collision with a stationary hydrogen atom. Before collision both atoms are in ground state and after collision they move together. What is the minimum
