Extra_Types of Waves

periodic wave

series of disturbances at regular time intervals

transverse wave

disturbance perpendicular to direction of travel

longitudinal wave

disturbance parallel to direction of travel

label amplitude, wavelength, crest, rest position, and trough

label rest position, compression, rarefaction

surface wave

displacement perpendicular and parallel (water)

electromagnetic wave

electrical and magnetic energy (light, radio, microwave), do not require a medium for travel

incident wave

approach a boundary

reflected waves

reflected

standing wave

incident waves interfering with reflected waves create pattern

constant amplitude and wavelength, reflect off fixed or free

specific “harmonic” frequencies (others will cause irregular motion)
