Question on: JAMB Physics - 2024
The energy of light of frequency 2.0 x 1015 Hz is (h = 6.63 x 10-34 Js)
A
3.33 x 10-18 J
B
1.33 x 10-18 J
C
1.33 x 10-19 J
D
3.33 x 10-19 J

Correct Option: B
The energy of a photon can be calculated using the following formula:
E = hf
- E is the energy of the photon
- h is Planck's constant (6.63 x 10-34 Js)
- f is the frequency of the light (2.0 x 1015 Hz)
Therefore:
E = (6.63 x 10-34 Js) * (2.0 x 1015 Hz)
E = 13.26 x 10-19 J ≈ 1.33 x 10-18 J
