Match the column-I (Fundamental Experiment) with Column-II (its conclusion) and select the correct option from the choices given below the list:
Column-I | Column-II | ||
(A) | Franck-Hertz | (I) | Particle nature of light |
(B) | Photo electric experiment | (II) | Discrete energy levels of atom |
(C) | Davision- Germer experiment | (III) | Wave nature of electron |
Text Solution
Verified by ExpertsC
The Franck-Hertz experiment was the first electrical measurement to clearly show the Quantum (discrete) nature of atoms. The experiment confirmed the quantum theory which predicted that electrons occupied only discrete energy levels.
Photoelectric effect experiment, supports the particle theory of light.
The Davision and Germer experiment showed that, electron beams can undergo diffraction when passed through the atomic crystal. This implies the wave nature of electrons as waves can exhibit interference and diffraction.
