Sound

At the end of this activity, students should be able to:
– define an acoustic wave
– calculate the wavelength of an acoustic wave given its speed and frequency
– explain why the speed of sound depends on the medium in which it propagates and understand why, when the medium is air, it also depends on the temperature
– describe the phenomena of echo, reverberation, and acoustic resonance
– describe the wavefront of an object moving at supersonic speed.
