B. Pulses & Periodic Waves
1. Pulse – single vibratory disturbance that moves from point to point
Medium only moves up and down
Which direction will segment X move as the wave passes through it? (1) down, only (2) up, only (3) down, then up, then down (4) up, then down, then up
a. When the pulse reaches a boundary with another medium, part is reflected and part is transmitted (goes through)
Dr. Dan Russell b. When a pulse reaches a fixed, unyielding boundary, then the pulse is completely reflected and inverted (180°) Transverse Wave - B. Barrett
2. Periodic Wave – series of evenly timed disturbances in a medium Periodic Wave -Wake Forest U.
C. Vibrations and Waves Vibrations - Philip Dukes - B.Y.U.
1. Longitudinal – medium moves parallel to the direction in which the wave travels
ex) sound - Guitar String
Guitar Vibrations - Fletcher
2. Transverse – vibrational disturbance which is perpendicular to the direction in which the wave travels
Transverse - St. Mary's Physics Online
Transverse Waves - University of Colorado Transverse and Longitudinal Waves - P.S.U. Unlike longitudinal, transverse waves can be oriented in many different planes.
Ex) water waves, seismic waves, electromagnetic waves (light, microwaves, radio waves) Electromagnetic Wave - Santa Barbara City College Vibrating Charges and Electromagnetic Waves - Physics 2000
Longitudinal, Transverse?
Transverse (Vibration perpendicular to wave travel)
