# Determine the energy of a photon whose frequency is 5.28 × 1017 Hz?

Nov 2, 2017

$E = 3.50 \times {10}^{16}$ J

#### Explanation:

The formula for determining the energy of a photon is $E = h f$, where

E is energy of the photon
h is planck's constant ( $6.63 \times {10}^{- 34}$)
f is the lights frequency

So substitute the values into the equation.

E =(6.63xx10^(-34))(5.28xx10^17  Hz)
$E = 3.50 \times {10}^{16}$ J
