What is the energy of a wave having a frequency of 5.71 x 1013 Hz?

Answer 1

`\huge{3.783 * {10}^( - 19) \: J}`

Step-by-step explanation:

The energy of the wave can be found by using the formula

E = hf

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 we have

E = 6.626 × 10-³⁴ × 5.71 × 10¹³

We have the final answer as

`3.783 * {10}^( - 19) \: J`

Hope this helps you
