Document Summary
Electromagnetic radiation form of energy transmission in which electric and magnetic fields as are propagated as waves through empty space, or through a medium. Wave disturbance that transmits energy through space or a material medium: energy is discontinuous (energy changes by a jump, or quantum, small particles of matter may at times display wave-like properties. Photoelectric effect phenomenon explaining that when light strikes the surface of metals, electrons are ejected. Heisenberg uncertainty principle cannot measure position and momentum accurately , simultaneously. Classical mechanics: objects = particles, know exact positions and velocities, energy is continuous. Quantum mechanics accounts for experiments related to atoms, electrons and light that cannot be explained by classical mechanics: objects = particles or waves, cannot know exact positions and velocities, energy is transferred in discrete units. Standing wave wave that remains in a constant position. Assigning quantum numbers: principle quantum number, n. only positive, non-zero number (n=1, 2, 3) Energy level/most probable distance of finding e- from.
