NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Photon energy | (i) h n |
| (b) Work function | (ii) eV 0 |
| (c) Threshold frequency | (iii) φ |
| (d) Photons emitted | (iv) N = P/E |
A
a-i, b-iii, c-ii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iv, b-ii, c-i, d-iii
D
a-iii, b-iv, c-i, d-ii
Correct Answer
Option A
Detailed Explanation
The energy of a photon is given by the formula E = h n, where h is Planck's constant and n is the frequency. The work function is denoted by φ, and the threshold frequency is related to it. The number of photons emitted can be calculated using N = P/E, where P is power and E is the energy per photon.
