A green laser pointer emits light with a wavelength of 529 nm. What is the energy of one of these photons

The energy of a photon emitted by the green light is 3.758 x 10⁻¹⁹ J

Explanation:

Given;

wavelength of the photon, λ = 529 nm = 529 x 10⁻⁹ m

The energy of a photon emitted by the green light is given by;

Where;

h is Planck's constant = 6.626 x 10⁻³⁴ J/s

c is speed of light = 3 x 10⁸ m/s

Substitute the given values;

Therefore, the energy of a photon emitted by the green light is 3.758 x 10⁻¹⁹ J
