NEET Physics Davisson-Germer Experiment Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Electron diffraction | (i) 1.76 × 10 11 C/kg |
| (b) Universality of cathode rays | (ii) High-frequency radiation |
| (c) Charge to mass ratio | (iii) Observed in the Davisson-Germer experiment |
| (d) Photoelectric effect | (iv) Independent of emitter material |
a-iii, b-iv, c-i, d-ii
a-i, b-ii, c-iv, d-iii
a-ii, b-iii, c-i, d-iv
a-iv, b-i, c-ii, d-iii
Correct Answer
Detailed Explanation
The Davisson-Germer experiment demonstrated electron diffraction (a-iii) and established the universality of cathode rays (b-iv) independent of the emitter material. The charge to mass ratio (c-i) of cathode rays is 1.76 × 10 11 C/kg, while the photoelectric effect is observed with high-frequency radiation (d-ii).
