Question

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

Answer 1

`E = 3.50 xx 10^(16)` J

Explanation:

The formula for determining the energy of a photon is `E = hf`, where

E is energy of the photon
h is planck's constant ( `6.63 xx 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 xx 10^(16)` J
