NEET Physics Photoelectric Effect Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Threshold Frequency | (i) Emission of electrons from a metal surface |
| (b) Photoelectrons | (ii) Linearly related to frequency |
| (c) Intensity of light | (iii) Dependent on the number of incident photons |
| (d) Frequency of incident light | (iv) Minimum frequency for photoemission |
a-iv, b-i, c-iii, d-ii
a-ii, b-iii, c-i, d-iv
a-iii, b-ii, c-iv, d-i
a-i, b-iv, c-ii, d-iii
Correct Answer
Detailed Explanation
The threshold frequency is the minimum frequency required for photoemission (a-iv). Photoelectrons are the emitted electrons from the metal surface (b-i). The intensity of light relates to the number of incident photons, which affects the photocurrent (c-iii). The frequency of incident light is directly related to the kinetic energy of the emitted photoelectrons (d-ii).
