The displacement vectors and , when added together, give the resultant vector , so that . Use the data in the drawing to find the magnitude R of the resultant vector and the angle that it makes with the x axis. R
Traveling Waves (have a well defined speed) Definition: Disturbance traveling through a medium (except light). While the wave propagates, the medium’s particles do not. Examples: - Sound waves - Ocean - Ripples - Earthquakes - Electromagnetic Waves Transverse & Longitudinal Waves Transverse: Displacement perpendicular to direction of travel (light) Longitudinal: Displacement parallel to direction of travel (springs, sound waves) Velocity Through a Medium Tension μ = linear density = mL v string√ μ *speed is independent of intensity of wave* Waves as a Function of Position and Time - Snapshot Graphs (taken as a snapshot in an instant of time during a wave) - History Graphs (follow one particular point, usually t
