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 metals (b) Photoelectrons (ii) Minimum frequency for electron emission (c) Intensity of radiation (iii) High voltage sparks enhancement (d) Hertz's experiment (iv) Increased number of emitted electrons
Choose the correct matching:
a-ii, b-i, c-iv, d-iii
a-i, b-ii, c-iii, d-iv
a-iii, b-iv, c-i, d-ii
a-iv, b-iii, c-ii, d-i
Correct Answer
Detailed Explanation
The threshold frequency is defined as the minimum frequency required for electron emission, which matches with option (ii). Photoelectrons are indeed the emitted electrons from metals (i), and increased intensity leads to more emitted electrons (iv), while Hertz's experiment enhanced high voltage sparks (iii).
