Final answer:
A photon of violet light has higher energy than a photon of yellow light due to its higher frequency in the electromagnetic spectrum.
Step-by-step explanation:
In the context of electromagnetic radiation, both yellow and violet light consist of photons, but they have different energies due to their frequencies. When considering light as a wave, each photon's energy is connected to its frequency—the higher the frequency, the higher the energy. In the spectrum of visible light, photons of violet light have higher energy than those of yellow light because violet light has a higher frequency. This can be expressed with the formula Ef = hf, where E is the energy of the photon, f is the frequency, and h is Planck's constant. Given that the energies for visible light range from 1.63 eV for red to 3.26 eV for violet, a photon of yellow light would have less energy than a photon of violet light, with yellow typically being closer to the lower-energy end of the spectrum.
