Document Summary
Light as waves and particles: light c=3 x 108 m/s: electromagnetic waves: oscillations of an electromagnetic field that travel at the speed of, frequency: number of oscillations per second v = c/ , amplitude (y): height of the wave; square gives wave intensity, light: stream of photons carry a fixed amount of energy and behave as waves or as particles, e = hv = hc/ ( kinetic energy, h = 6. 63 x 10 34 js (planck"s constant, energy of light can be absorbed/emitted only as small discrete portions (individual photons) frequencies, visible light: 400 750nm (electromagnetic radiations are only distinguishable by their, emission spectrum: h atoms emit light with certain wavelengths, balmer series: visible light (violet, blue, blue green, red, lyman series: uv light, paschen series: infrared light, rydberg formula predicts all wavelengths of light emitted by excited h atoms didn"t explain why only certain wavelengths are emitted.
