Frank and Hertz experiment proves that
- A light moves in the form of waves as well as particles
- B the electron does not radiate energy, while moving in an orbit
- C the energy states of an atom are quantised
- D the whole of the positive charge of the atom is concentrated in the nucleus
Answer & Solution
Correct Answer
(C) the energy states of an atom are quantised
Step-by-step Solution
Detailed explanation
Frank an Hertz's experiment demonstrated the existence of excited states in mercury atoms. It confirms the prediction of quantum theory that electrons occupy only discrete, quantised energy states.
