Question

Green light has a frequency of about 6.00×1014s−1. What is the energy of a photon of green light?

Answer 1

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.
