NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Easy-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Work function of caesium | (i) 6.63 × 10<sup>-34</sup> J s |
| (b) Threshold frequency | (ii) 2.14 eV |
| (c) Energy of photon | (iii) E = h n |
| (d) Maximum kinetic energy | (iv) eV<sub>0</sub> = h n - φ |
A
a-ii, b-i, c-iii, d-iv
B
a-i, b-ii, c-iv, d-iii
C
a-ii, b-iii, c-i, d-iv
D
a-iv, b-ii, c-i, d-iii
Correct Answer
Option A
Detailed Explanation
The work function of caesium is indeed 2.14 eV, the threshold frequency relates to the photon energy equation, and the maximum kinetic energy is derived from Einstein's photoelectric equation, eV0 = h n - φ, where h is Planck's constant and φ is the work function.
