NEET Physics Photoelectric Effect Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Photoelectric effect | (i) Emission of electrons due to light |
| (b) Work function | (ii) Minimum energy required for emission |
| (c) Threshold frequency | (iii) Frequency below which emission does not occur |
| (d) Instantaneous process | (iv) Emission occurs without delay |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iv, b-iii, c-ii, d-i
a-iii, b-iv, c-i, d-ii
Correct Answer
Detailed Explanation
The photoelectric effect is defined as the emission of electrons when light of suitable frequency strikes a metal, which aligns with matching (a-i). The work function is indeed the minimum energy required for emission (b-ii), and the threshold frequency is the frequency below which no emission occurs (c-iii). The process is instantaneous, meaning that emission occurs without delay (d-iv).
