Match list-I (Fundamental Experiment) with List-II (its conclusion) and select the correct option from the choices given below the list: List-I List-II A Franck-Hertz Experiment (i) Particle nature of light B Photo-electric experiment (ii) Discrete energy levels of the atom C Davison-Germer Experiment (iii) Wave nature of electron (iv) Structure of atom

Options

  1. AA - i v   ; B - i i i ; C - ( i i )
  2. BA - i ; B - i v ; C - ( i i i )
  3. CA - i i ; B - i v ; C - ( i i i )
  4. DA - i i ; B - i ; C - ( i i i )

Correct answer

D. A - i i ; B - i ; C - ( i i i )

Step-by-step solution

Frank-Hertz's experiment demonstrated the existence of excited states in mercury atoms helping to confirm the quantum theory which predicted that electrons occupied only discrete quantized energy states. The photo-electric experiment demonstrated that photon is the particle of light, which can transfer momentum and energy due to collision. Davidson-Germer's experiment shows the wave nature of electrons.
