An electron and a proton are separated by a large distance and the electron approaches the proton with a kinetic energy of 2 eV . If the electron is captured by the proton to form a hydrogen atom in the ground state, what wavelength (in Å ) photon would be given off?

Correct answer

796

Step-by-step solution

Energy of hydrogen atom =-13.6 ev aligned & h c =13.6+2 & 796 Å aligned
