NEET Chemistry (general) Match the Following Question
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
Choose the correct matching:
a-iii, b-i, c-iv, d-ii
a-ii, b-iv, c-iii, d-i
a-iv, b-ii, c-i, d-iii
a-iii, b-ii, c-i, d-iv
Correct Answer
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).
