What is the frequency of a photon of light (in Hz) that has an energy of 2.50 x 10-18 J?

The answer is

Explanation:

The frequency of the photon can be found by using the formula

where

E is the energy

f is the frequency

h is the Planck's constant which is

6.626 × 10-³⁴ Js

From the question

E = 2.50 × 10^-18 J

So we have

We have the final answer as
