NEET Physics Photoelectric Effect Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Work function | (i) Minimum energy required to release an electron |
| (b) Maximum kinetic energy | (ii) Proportional to the intensity of radiation |
| (c) Threshold frequency | (iii) Frequency below which photoelectrons are not emitted |
| (d) Intensity of radiation | (iv) Independent of maximum kinetic energy |
a-i, b-iv, c-iii, d-ii
a-ii, b-iii, c-i, d-iv
a-iii, b-i, c-iv, d-ii
a-i, b-ii, c-iv, d-iii
Correct Answer
Detailed Explanation
The work function is the minimum energy required to release an electron, and the maximum kinetic energy is independent of the intensity of radiation. The threshold frequency is indeed the frequency below which photoelectrons are not emitted. Intensity of radiation is proportional to the number of quanta but not to the maximum kinetic energy of emitted electrons.
