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) Photonic energy (i) 2.14 eV (b) Work function of caesium (ii) 5.0 × 10^15 photons per second (c) Number of emitted photons (iii) 3.98 × 10^-19 J (d) Threshold frequency (iv) 6.0 × 10^14 Hz

Choose the correct matching:

A

a-iii, b-i, c-ii, d-iv

B

a-ii, b-iv, c-i, d-iii

C

a-i, b-iv, c-iii, d-ii

D

a-iv, b-ii, c-iii, d-i

Correct Answer

Option A

Detailed Explanation

The energy of a photon is calculated to be 3.98 × 10^-19 J, and the work function of caesium is given as 2.14 eV, which aligns with the correct matches in option A. The number of emitted photons is calculated to be 5.0 × 10^15 photons per second, and the threshold frequency corresponds to 6.0 × 10^14 Hz.
