What is the energy of a photon using the given frequency and Planck's
nydimaria [60]

Answer:

Energy of photon is 34.45 ×10⁻¹⁹ J.

Explanation:

Given data:

Frequency of photon = 5.2×10¹⁵ s⁻¹

Plancks constant = 6.626×10⁻³⁴ Js

Energy of photon = ?

Solution:

Formula:

E = h.f

by putting values,

E =  6.626×10⁻³⁴ Js × 5.2×10¹⁵ s⁻¹

E = 34.45 ×10⁻¹⁹ J

Thus, energy of photon is 34.45 ×10⁻¹⁹ J.
