WBJEE 2015 Physics Solved Paper

A photon of wavelength 300 nm interacts with a stationary hydrogen atom in ground state. During the interaction,whole energy of the photon is transferred to the electron of the atom. State which possibility is correct. (Consider,Planck’s constant = 4×10–15 eVs, velocity of light = 3×108 m/s, ionization energy of hydrogen = 13.6eV)
