Question

Determine the energy in joules of a photon whose frequency is 3.75 x 1017 Hz.

Plz help my grade and life depend on it

Answer 1

The energy of photon is 24.86×10⁻¹⁷ J

Step-by-step explanation:

Given data:

Frequency of photon = 3.75×10¹⁷ Hz

Energy of photon = ?

Solution:

Formula:

E = hf

h = planck's constant = 6.63×10⁻³⁴ Js

Now we will put the values in formula.

E = 6.63×10⁻³⁴ Js × 3.75×10¹⁷ Hz

Hz = s⁻¹

E = 24.86×10⁻¹⁷ J

Thus, the energy of photon is 24.86×10⁻¹⁷ J
