1. A periodic longitudinal wave that has a frequency of 20.0 Hz travels along a coil spring. if the distance between successive compressions is 0.4m, what is the speed of the wave?


2. v= wavelength times frequency



3. v= wavelength times frequency
= 0.4 * (20)
= 8 m/s ------ I'm not sure if this is right.
