Question

Quizplus · Accepted Answer

The energy of a photon is given by E = hf, where h is Planck's constant (6.63 × 10^-34 J⋅s) and f is the frequency (2450 MHz or 2.45 × 10^9 Hz). Converting the energy from joules to electron volts (1 eV = 1.602 × 10^-19 J), the energy is approximately 1.02 × 10^-5 eV.
