Question

Calculate the energy of a photon of electromagnetic radiation that has a frequency of 9.50 x 1013 Hz. Planks constant is 6.626 x 10-34.​

Answer 1

`\huge{ \boxed{6.294 * {10}^( - 20) \: 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;

f = 9.5 × 10¹³ Hz

`\therefore \: E = 6.626 * {10}^( - 34) * 9.50 * {10}^(13 \\ ) \\ = 6.295 * {10}^( - 20)`
