Davisson-Germer, Uncertainty, Compton & X-Rays
Match List - I (Experiment performed) with List - II (Phenomena discovered/associated) and select
the correct option from the options given below the lists:
| List - I | List - II |
| (a) Davisson and Germer Experiment | (i) Wave nature of electrons |
| (b) Millikan’s oil drop experiment | (ii) Charge of an electron |
| (c) Rutherford experiment | (iii) Quantisation of energy levels |
| (d) Franck - Hertz experiment | (iv) Existence of nucleus |
Show answer and solution
Answer: (b)
- Davisson and Germer: electron diffraction, so wave nature of electrons, (a)-(i).
- Millikan oil drop: charge of the electron, (b)-(ii).
- Rutherford alpha scattering: existence of the nucleus, (c)-(iv).
- Franck-Hertz: discrete energy losses, so quantised energy levels, (d)-(iii).
- So the answer is (b).
