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 |
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).
