Question

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 =4.1×1015eVs, velocity of light =3×108m/s, ionisation energy of hydrogen = 13.6 eV)
  1. Electron will be knocked out of the atom
  2. Electron will go to any excited state of the atom
  3. Electron will keep orbiting on the ground state of the atom
  4. Electron will go only to first excited state of the atom

A
Electron will be knocked out of the atom
B
Electron will keep orbiting on the ground state of the atom
C
Electron will go to any excited state of the atom
D
Electron will go only to first excited state of the atom
Solution
Verified by Toppr

Total energy of the photon =hcλ=4.1×1015eVs×3×108m/s300×109m=4.1eV
Since the energy required by the hydrogen atom in moving from first orbit to second orbit is 10.2 eV, the electron won't get out of the orbit.

Q5
In a sample of hydrogen atom in ground state, electrons make transition from ground state to a particular excited state where path length is five times de-broglie wavelength, electrons make back-transition to the ground state producing all possible photons. If photon having 2nd highest energy of this sample can be used to excite the electron in a particular excited state of Li2+ atom then find the final excited state of Li2+ atom
