Answer:
E = hf
Explanation:
A photon is a particle which represents a 'quantum of light' or other electromagnetic radiation. These are particles that carry no mass and move at the speed of light.
The energy of a photon (E) can be given by Planck's equation where:
[tex]E = hf[/tex]
h = planck's constant = 6.626 *10⁻³⁴ Js
f = frequency of photon = [tex]\frac{c}{\lambda }[/tex]
where λ = wavelength of photon.
Therefore, [tex]E= \frac{hc}{\lambda }[/tex]
