What is the frequency of a wave having 4.90 x 10 -12 J of energy?

The answer is

Explanation:

To find the frequency of the wave we use 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 = 4.90 × 10-¹² J

So we have

We have the final answer as

Hope this helps you
