Question

Quizplus · Accepted Answer

The energy equation for a photon is E=hf, where E is energy, h is Planck's constant, and f is frequency.

We are given the frequency of the photon as 8.21 × 10^15 s^-1.

We can use Planck's constant, h = 6.626 × 10^-34 J*s, in the energy equation to calculate the energy of the photon:

E = (6.626 × 10^-34 J*s) × (8.21 × 10^15 s^-1) = 5.44 × 10^-18 J

Therefore, the answer is D) 5.44 × 10^-18 J.
