The wavelength of a beam of light is 24 mm. What is the energy of one of its photons?
Added by Jose Luis M.
Step 1
We need to find the frequency of the light using the wavelength. We can use the formula: $$v = \frac{c}{\lambda}$$ where $v$ is the frequency, $c$ is the speed of light ($3 \times 10^8$ m/s), and $\lambda$ is the wavelength. Show more…
