Its quantum operator is negative i times h bar gradient. For a photon, this quantity is equal to Planck's constant divided by wavelength, which is the same as energy divided by the speed of light.
Its quantum operator is negative i times h bar gradient. For a photon, this quantity is equal to Planck's constant divided by wavelength, which is the same as energy divided by the speed of light. Its derivative with respect to time is equal to net force, a fact which, when combined with Newton's Third Law, shows why this quantity is conserved. The net change in this quantity for an object equals the total impulse upon it. Identify this quantity whose SI unit is kilogram meters per second.
