3.98 x 10⁻¹⁹ Joule

Further explanation

Given:

The green light has a frequency of about 6.00 x 10¹⁴ s⁻¹.

Question:

The energy of a photon of green light (in joules).

The Process:

The energy of a photon is given by $\boxed{\boxed{ \ E = hf \ }}$

E = energy in joules
h = Planck's constant 6.63 x 10⁻³⁴ Js
f = frequency of light in Hz (sometimes the symbol f is written as v)

Let us find out the energy of the green light emitted per photon.

$\boxed{ \ E = (6.63 \times 10^{-34})(6.00 \times 10^{14}) \ }$

Thus, we get a result of $\boxed{\boxed{ \ E = 3.98 \times 10^{-19} \ J \ }}$

Notes

When an electron moves between energy levels it must emit or absorb energy.
The energy emitted or absorbed corresponds to the difference between the two allowed energy states, i.e., as packets of light called photons.
A higher energy photon corresponds to a higher frequency (shorter wavelength) of light.
