Heinrich Hertz’s production in 1888 of what are now called radio waves, his verification that these waves travel at the same speed as visible light, … WebThe range of photon energies for visible light from red to violet is 1.63 to 3.26 eV, respectively (left for this chapter’s Problems and Exercises to verify). These energies are on the order of those between outer electron shells in atoms and molecules. This means that these photons can be absorbed by atoms and molecules.
Electromagnetic spectrum - Wikipedia
WebThe energy of light (or photon energy), E, is inversely proportional to the wavelength by the equation: E = hc/ l (equation 1) where h is Planck's constant (6.6261 x 10 -34 J*s) and c is the speed of light (2.9979 x 10 8 m/s). Photon energy can be expressed using any unit of energy such as the electronvolt (eV) or the Joule (J).
