Question

A periodic longitudinal wave that has a frequency of 20.0 Hz travels along a coiled spring toy. If the distance between successive compressions is 0.600 m, what is the speed of the wave?

Answer 1

Answer:

The speed of the wave = 12.0 m/s

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
