What does PLANCKS CONSTANT mean? γ. g, Ctrl+G. ABOUT. The Ħ is a Latin alphabet meaning reduced Planck constant. "h-bar", aka the "reduced Planck's constant" is sometimes called the "quantum of angular momentum". The idea behind its dicovery, that energy can be expressed in discrete units, or quantized, proved fundamental for the development of quantum mechanics.

According to traditional classical quantum theory, due to the prior existence of the Planck constant, considered a universal constant, it is thought that the energy of a photon can be determined if its frequency is known, and the wavelength of a quantum can be determined if its momentum is known (E = hv and λ = h/p).
