Friday, September 23, 2016 Chemistry, Week 5 6.3: Development of Quantum Theory Behavior in the Microscopic World - p = mv - classical trajectory—typical behavior - when waves interact w/ each other, they show interference patterns not displayed by macroscopic particles - λ = h/mv = h/p • called the de Broglie wavelength • characteristics of particles of other bodies (not electromagnetic radiation) - circular orbit: 2πr = n λ, n = 1, 2, 3… - de Broglie related to wavelength to the momentum and velocity • 2πr = n λ = nh/p = nh/mv = nhr/mvr = nhr/L • also arranged by: L = nh/2π = nh - classical angular momentum L: L = rp = rmv (for a cirulcar motion) - It is fundamentally impossible to determine simultaneously and exactly both the momen
