Document Summary
Tenth series: wave, sound wave: at zion national park a loud shout produces an echo 1. 85 s later from a colourful sandstone cliff, four waves are described by the following equations, all distances measured in centimeters and all. How far away is the cliff? time in seconds y y y y a b c d. Rank the waves in order of increasing: frequency, wavelength, in fig below, pipe a is made to oscillate in its third harmonic by a small internal sound source. Sound emitted at the right end happens to resonate four nearby pipes, each at with only one open end ( they are not drawn to scale). Pipe b oscillates in its lowest harmonic, pipe c in its second lowest harmonic, pipe d in its third lowest harmonic, and pipe e in its fourth lowest harmonic. 0: at a distance of 30m from a jet engine, the sound intensity level is 130 db.
