Calculate the energy, in electron volts, of a photon whose frequency is the following.

(a) 585 thz
(b) 3.50 ghz
(c) 40.0 mhz

planck's equation for the energy of a photon is e = hf, where f is the frequency and h is planck's constant. we use 1 ev = 1.60 ✕ 10−19 j for units of energy.

(a) for the energy of the photon at a frequency of 585 thz, we have e = hf
