This means that … WebbIn Equation 6.22, ℏ = h / 2 π ℏ = h / 2 π is the reduced Planck’s constant (pronounced “h-bar”), which is just Planck’s constant divided by the factor 2 π. 2 π. Vector k → k → is called the “wave vector” or propagation vector (the direction in which a photon is moving). The propagation vector shows the direction of the photon’s linear momentum vector.
