JEE Main 2015 — Dual Nature of Matter Question with Solution
JEE Main 2015 (04 Apr)
Question
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 |

Correct answer
D
Step-by-step explanation
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.
