Question

Quizplus · Accepted Answer

Red light has the lowest energy photons among the options given. This is because in the visible spectrum, red light has the longest wavelength and, according to the relationship E = hc/λ (where E is energy, h is Planck's constant, c is the speed of light, and λ is wavelength), longer wavelengths correspond to lower energy.
