An electron and proton are separated by a large distance. The electron starts approaching the proton with energy 3 eV. The proton captures the electrons and forms a hydrogen atom in second excited state. The resulting photon is incident on a photosensitive metal of threshold wavelength 4000Å What is the maximum kinetic energy of the emitted photoelectron?

An electron approaches a fixed proton from a large distance with a kinetic energy of 12.2 eV. The electron gets captured by the proton to form a hydrogen atom in an excited state and a photon of wavelength lambda_(1) = 796 Å is emitted. Later, the hydrogen atom de-excites by emitting a single photon of wavelength lambda_(2) . Find lambda_(2) . [Take h = 6.62 xx 10^(– 34) Js, c = 3 xx 108 m//s ]
