The sequence below comes from this topic's published material. Sections expand or contract with the subject instead of forcing every lesson into the same five-step mold.
Structure
The structure of Photons, Wavelength & Frequency
The key relations are c = λν and E = hν, where c is the speed of light, λ wavelength, ν frequency, h Planck's constant, and E photon energy. Shorter-wavelength photons therefore carry more energy individually.
