Question

A radio wave has a frequency of 8.6 × 10⁸ Hz. What is the energy of one photon of this radiation? (h = 6.63 × 10^-34 J • s) A) 7.7 × 10^-43 J B) 2.3 × 10^-34 J C) 5.7 × 10^-25 J D) 1.7 × 10^-16 J E) > 10^-15 J

Quizplus · Accepted Answer

The energy of a photon can be calculated using the formula E = hf, where E is the energy, h is Planck's constant (6.63 × 10^-34 J•s), and f is the frequency of the radiation (8.6 × 10^18 Hz). Substituting the given values, E = (6.63 × 10^-34 J•s) × (8.6 × 10^18 Hz) = 5.7 × 10^-15 J.
