In this lecture I define a photon as both a wave and a particle of light, introduce the Planck Constant as a way we calculate the amount of energy a photon contains based on its frequency and wavelength, and give four examples of calculating the energy, frequency, and wavelength of a photon. I also explain how to convert a Joule to an electron volt (eV).
What it means for light to be both a wave and a particle: • Is light a particle or a wave? - Colm...
