If Planck's constant (h) were zero, the energy associated with light waves would also be zero, leading to significant implications for wave-particle duality. The equation for De Broglie's wavelength, which relies on h, indicates that if h equals zero, the concept of wave-particle duality would collapse, reverting quantum physics to classical physics. In this scenario, waves would behave purely as waves, and particles would behave purely as particles, eliminating the dual nature observed in quantum mechanics. The discussion highlights the fundamental role of Planck's constant in defining quantum behavior. Overall, if h were zero, the universe would lack the complexities of quantum phenomena.
