Calculate the energy of a photon of this light wave in joules. [Show all calculations, including the equation and substitution w
Ket [755]

The energy of the photon from the calculation performed is 3.5 * 10^-16 J.

<h3>What is a photon?</h3>

A photon is a packet of light. It was derived from the theory of Albert Einstein. The energy of a photon is obtained from; E = hc/λ

  • h= Plank's constant
  • c = speed of light
  • λ = wavelength

Now we have that;

E = 6.6 * 10^-34 * 3 * 10^8/562 * 10^-9

E = 3.5 * 10^-16 J

Missing parts:
