LING 330 Lecture Notes - Lecture 13: Standing Wave, Vocal Tract
Document Summary
How long does it take for one complete cycle? . How many times does the cycle repeat in unit of time? . In dry air at 20 : 34321 cm/s = 343. 21 m/s = 1,236 km/h. How fast does the wave travel in this medium? . How far does a wave travel in 1 period of time? . Period (t), frequency (f), and wavelength ( ) are all related to each other. The speed of the wave is independent of t, f , and . Speed of sound is related to physical properties of the medium. A wave will travel until through a medium until one of two things happen: It hits an object (and when it does hit an object, it bounces back) When a wave is reflected back, a standing wave can happen. The amplitude of a standing wave is twice that of the individual waves when the peaks and valleys line up.
