What is the frequency of a photon whose energy is 3.4 x 10-19 )? (h = 6.626 x 10-34 Js)

Frequency of photon is 0.513×10¹⁵ s⁻¹

Explanation:

Given data:

Energy of photon = 3.4×10⁻¹⁹ J

Frequency of photon = ?

Planck's constant = 6.63 × 10⁻³⁴ Js

Solution:

Formula:

E = hf

3.4×10⁻¹⁹ J = 6.626 × 10⁻³⁴ Js × f

f =  3.4×10⁻¹⁹ J / 6.626 × 10⁻³⁴ Js

F = 0.513×10¹⁵ s⁻¹

Frequency of photon is 0.513×10¹⁵ s⁻¹.
