The energy of a photon : 7.645 x 10⁻³⁴ J
<h3>Further explanation </h3>Radiation energy is absorbed by photons
The energy in one photon can be formulated as
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
f = c / λ , Hz
c = speed of light
= 3.10⁸ m/s
λ = wavelength ,m
wavelength λ of 2.60 ✕ 10⁻⁸ m
The energy :
