Document Summary
Day 1: waves [monday, jan 09] sound waves study guide 2 (acoustics, vibrating strings) electromagnetic waves study guides 3-4 (light, x-rays, infra-red) quantum mechanical waves study guide 4-6 (motion of elementary particles/waves) notation equations on formula sheet. What"s in a wave? energy carrying disturbance produced by oscillations or vibrations no overall forward movement of matter. Waves have characteristic properties which can be discussed, such as wavelength, period, wave speed, etc. Em waves probability waves light, radio, (cid:541) waves, radar quantum description of particles electrons in an atom properties of a travelling wave . Waves move energy, not matter! particles oscillate about an equilibrium point as the wave moves" forward two types transverse . Movement of oscillating particles is perpendicular to the direction of the wave propagation i. e. water, string, light longitudinal . Day 3: waves [jan 13] outline review (brief) travelling waves and the wave equation new today standing waves.
