NEET Physics Photoelectric Effect Match the Following Question
Match Column-I with Column-II.
Column-I Column-II (a) Hertz's discovery (i) Electrons emitted due to light (b) Threshold frequency (ii) Observed increase in sparks (c) Photoelectrons (iii) Minimum frequency for emission (d) Intensity of light (iv) Directly proportional to photocurrent
Choose the correct matching:
a-ii, b-iii, c-i, d-iv
a-ii, b-iv, c-iii, d-i
a-iii, b-ii, c-iv, d-i
a-i, b-ii, c-iv, d-iii
Correct Answer
Detailed Explanation
Hertz's discovery in 1887 showed that illuminating a metal enhances spark discharge (a-ii). The threshold frequency is the minimum frequency required for photoemission (b-iii). Photoelectrons are the electrons emitted when light shines on a metal surface (c-i), and the intensity of light relates directly to the photocurrent produced (d-iv).
