Question

Determine the energy of a photon whose frequency is 5.94x10^17Hz. Answer in units of J

Answer 1

`\huge{ 3.935 * {10}^( - 16) J}`

Step-by-step explanation:

The energy of the photon 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 the frequency is

5.94x10^17Hz

We have

`E = 6.626 * {10}^( - 34) * 5.94 * {10}^(17) \\ = 3.935 * {10}^( - 16) J`

Hope this helps you
