Document Summary

Light & other electromagnetic radiation have both wave-like & particle-like properties. Atomic spectra show that electrons also have wave-like properties - in addition to being particles. Quantum mechanics describes this quantization & explains the . & resulting properties of atoms & ions . Oscillating electric & magnetic fields, propagating through space direction of propagation is orthogonal to electric & magnetic fields. Wavelength, = crest to crest (or trough to trough) distance. Frequency, = (# of crests passing a reference point) Units of are cycles per second or hertz, hz (elapsed time) In s. i. units, we omit cycle 1 hz = 1 s 1. Waves move past reference point each second. Each wave covers a distance of . = distance covered per second i. e. the speed, v, of traveling wave. All electromagnetic waves travel with the same, constant, speed: v = c = 3. 00 108 m s 1 c = = c/ or = c/ .
