Echo method & microphone/oscilloscope method
Sound bounces back from walls
Double the distance (to wall and back)
speed=distancetime\text{speed} = \frac{\text{distance}}{\text{time}}speed=timedistance
wave speed=frequency×wavelength\text{wave speed} = \text{frequency} \times \text{wavelength}wave speed=frequency×wavelength
2 microphones, oscilloscope, loudspeaker
One wavelength apart
Shallow tank, vibrating paddle, strobe light
Freezes waves to measure wavelength accurately
Better accuracy & reduce measurement errors
