Question

What is the energy of a photon with a frequency of 8.34 x 10^14 hz, in joules?

Answer 1

E = 5.52 x 10⁻¹⁹ J

Step-by-step explanation:

The formula for energy of a photon, E, is:

`E = hf`

where h is Plank's constant = 6.62 x 10 ⁻³⁴ .

Using the formula:

E = 6.62 x 10⁻³⁴ x 8.34 x 10¹⁴

= 5.52 x 10⁻¹⁹ J
