Document Summary
Wave properties: wavelength and frequency are related by, c = v, is wavelength (in meters, v id frequency (in hertz or s-1, c is the speed of light in vacuum, c = 2. 998 x 108 m/s. Rydberg equation: 1 / = r (1/n1. 2 1/n2: r = 1. 097 x 10-2 nm-1. Atom spectra interpretation; bohr: ex: calculate ionization energy for h atom, h (g) h+ (g) + e, means change is from n=1 to n=infinity. It"s radiation that has properties of waves (wavelength, frequency) and particles (momentum) Doubling he frequency would cut by half; inversely proportional. Determined that electrons live in discrete orbitals (energy levels) Electrons can move between these orbitals either by absorbing or emitting energy. Broglie proposed that matter including macroscopic particles, like people, have a wavelength. The bigger the mass, the smaller the wavelength. Quantum numbers n = principle quantum number (energy,size)
