Answer:
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;
[tex]E = hf\\\\E = h(\frac{c}{\lambda} )\\\\[/tex]
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;
[tex]E = h(\frac{c}{\lambda} )\\\\E =(6.626*10^{-34})(\frac{3*10^8}{529*10^{-9}} )\\\\E = 3.758 *10^{-19} \ J[/tex]
Therefore, the energy of a photon emitted by the green light is 3.758 x 10⁻¹⁹ J
