Type: Match the Following-match the column-Medium-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Thermionic emission | (i) Emission of electrons due to heating |
| (b) Photoelectric effect | (ii) Emission of electrons by incident light |
| (c) Work function | (iii) Minimum energy for electron emission |
| (d) Electron diffraction | (iv) Wave nature of particles |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iv, b-iii, c-ii, d-i
D
a-iii, b-i, c-ii, d-iv
Correct Answer
Option A
Detailed Explanation
Thermionic emission is the process where electrons are emitted from a metal surface due to heating, while the photoelectric effect involves the emission of electrons due to incident light. The work function is defined as the minimum energy required for electron emission, and electron diffraction illustrates the wave nature of particles.
