NEET Chemistry (general) Match the Following Question
Type: Match the Following-match the column-Easy-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Threshold frequency | (i) Energy of emitted electrons |
| (b) Kinetic energy | (ii) Light intensity proportionality |
| (c) Photoelectric effect | (iii) Minimum frequency for emission |
| (d) Ejected electrons | (iv) Classical physics limitations |
A
a-iii, b-i, c-iv, d-ii
B
a-ii, b-iv, c-iii, d-i
C
a-iv, b-ii, c-i, d-iii
D
a-iii, b-ii, c-i, d-iv
Correct Answer
Option A
Detailed Explanation
The threshold frequency is the minimum frequency below which no electrons are emitted in the photoelectric effect (a-iii). The kinetic energy of the emitted electrons is related to the energy of the incoming photons (b-i). The photoelectric effect shows limitations of classical physics in explaining electron emission based on light intensity (c-iv). The number of ejected electrons is indeed proportional to the intensity of light (d-ii).
