How fast energy is transferred through a substance
Two microphones, oscilloscope, loudspeaker, signal generator
The wavelength of the sound wave
v=f×λv = f \times \lambdav=f×λ (speed = frequency × wavelength)
Signal generator, dipper, strobe light
Strobe frequency matches water wave frequency
Measure distance between crests, divide by number of wavelengths
Peak frequency of sound waves produced
Three times (then calculate average frequency)
Wavelength is twice the length of the rod
Metres per second (m/s)
Hertz (Hz)
Metres (m)
