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
Choose the correct matching:
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).
