Answer:
The speed of the wave = 12.0 m/s
Step-by-step explanation:
The frequency along a coiled spring toy, f = 20 Hz
The distance between two successive compressions is the wavelength of the wave
The wavelength, λ = 0.600 m
The speed of the wave is given as:
v = λf
v = 20(0.6)
v = 12.0 m/s
The speed of the wave = 12.0 m/s
