A photon with a frequency of 2.3 * 10¹⁶ Hz has how many joules of energy? A) 1.5 * 10^-17 B) 1.5 * 10¹⁷ C) 3.5 * 10^-17 D) 3.5 * 10¹⁷ E) 3.0 * 10⁸

Question

Quizplus · Accepted Answer

The energy of a photon is given by the equation E = hf, where h is Planck's constant (6.626 x 10^-34 J·s) and f is the frequency of the photon. Using the given frequency of 2.3 x 10^16 Hz, the energy E = (6.626 x 10^-34 J·s)(2.3 x 10^16 Hz) = 1.524 x 10^-17 J, which is closest to the value given in option A.
