Description
Quantum Physics: Plank’s Constant If Planck’s constant is zero: - First, energy of radiation would be zero. E = h x f. So, h = E/f where h is Planck’s constant, E is energy and f is the frequency of the particle. If that is 0=E/f that means that E= 0 - Second, particles would not have wave properties . Matter wave length (m) = h / mv where h is Planck’s constant, m is mass and v is velocity. When h equals 0, matter wave length would be zero as well. - Third, the uncertainty principle would be meaningless. (Δx)·(Δv) ≈ h/m whereΔx is uncertainty in position, Δv is uncertainty in velocity, h is Plank’s constant and m is mass. If h equals 0, (Δx)·(Δv) would equals 0. Then, there would be no uncertainty because we could predict both velocity and position with pinpoint accuracy. - Forth, when h = 0, there would be no quantum physics and Newtonian physics would be valid. Comments about Planck's Constant 1) Planck's constant proves to have a very small value. 2) The quantity, h, is the central constant of quantum physics. 3) In a universe
