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. (Take, Planck's constant 
, velocity of light 
, ionisation energy of hydrogen 
)
Text Solution
Verified by ExpertsThe correct answer is:
D
The energy of the photon,
The ionisation energy is 13.6 eV which is greater than the energy of photon, so electron cannot be knocked out or into excited state. Thus, it will keep orbiting in ground state of the atom.
