NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Thermionic emission | (i) Emission of electrons due to heat |
| (b) Photoelectric effect | (ii) Emission of electrons due to light |
| (c) Work function | (iii) Minimum energy required for electron emission |
| (d) Threshold frequency | (iv) Minimum frequency for the photoelectric effect |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iii, b-iv, c-i, d-ii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
Thermionic emission refers to the emission of electrons due to heat, while the photoelectric effect involves emission due to light. The work function is the minimum energy required for electron emission, and the threshold frequency is the minimum frequency necessary for the photoelectric effect to occur.
