The frequency of a photon that has an energy of 8.5 × 10^-12 J is ________ s^-1. A)1.3 × 10²² B)1.8 × 10^-16 C)2.5 × 10^-15 D)5.4 × 10^-8 E)2.5 × 10¹⁵

Question

Quizplus · Accepted Answer

The energy of a photon is given by E = hf, where E is the energy, h is Planck's constant (6.63 × 10^-34 J s), and f is the frequency. Solving for f, we get f = E/h. Plugging in the given energy, we get f = (8.5 × 10^-12 J) / (6.63 × 10^-34 J s) = 1.3 × 10^22 s^-1.
