Waves-Physics Exam Questions with Latest Update

Mechanical Waves - ANSWER-waves that travel along a spring Wave - ANSWER-a vibratory (periodic) disturbance that is transmitted through a material or through space Transverse Wave - ANSWER-particles of the medium exhibit SHM about a rest position perpendicular to the direction of the motion of the wave Longitudinal Wave - ANSWER-a disturbance causes the particles of the material to vibrate in SHM in a direction parallel to the direction of motion of the wave Surface Wave - ANSWER-motions of particles are both parallel and perpendicular to the direction of the motion of the wave Period - ANSWER-the time it takes for the wave's motion to repeat itself Frequency - ANSWER-the number of times the motion repeats itself in a time interval of one unit of time is known as the frequency of the wave. (Hz) Hz - ANSWER-cycles per second (or s^-1) Period= - ANSWER-1/(frequency) Amplitude - ANSWER-the maximum displacement of any particle in the medium relative to its rest position Crest - ANSWER-the maximum upward displacement Trough - ANSWER-the maximum downward displacement V= - ANSWER-(frequency)(wavelength) Power is relative to - ANSWER-(frequency)^2 Same period= - ANSWER-same length Nodes - ANSWER-the points that do not move (when two waves "combine") Antinodes - ANSWER-crest-trough combinations Pulse - ANSWER-a single vibratory disturbance (pulled and then released)
