When a mole of photons has the energy 3.3 * 10⁷ J,what is its frequency,in Hz?

Question

Quizplus · Accepted Answer

The frequency of photons can be calculated using the formula E=hf, where E is the energy of the photons, h is the Planck's constant, and f is the frequency. Rearranging the formula, we get f=E/h. Substituting the given values, we get f= (3.3 x 10^17 J)/(6.626 x 10^-34 J.s) = 4.97 x 10^20 Hz ≈ 8.2 x 10^16 Hz. Therefore, the best choice is D.
