What is the energy of a photon with a frequency of 3.8 * 10¹⁴ Hz? A) 1.5 * 10^-15J B) 3.8 * 10¹⁴J C) 8.3 * 10^-14J D) 3.8 * 10^-19J E) 1.5 * 10^-15J

Question

Quizplus · Accepted Answer

The energy of a photon can be calculated using the formula E = hf, where h is the Planck constant (6.626 x 10^-34 J s) and f is the frequency of the photon in Hertz. Therefore, the energy of a photon with a frequency of 3.8 x 10^14 Hz can be calculated as:
E = (6.626 x 10^-34 J s) x (3.8 x 10^14 Hz)
E = 2.52 x 10^-19 J
This value is closest to option B, which is 3.8 x 10^-19 J.
