Are the following statements correct?
We observe longitudinal waves on a coil spring. At the compressions, the displacement of the particles from the equilibrium position is zero.
At the rarefactions, the displacement of particles from the equilibrium position is greatest.
A sound source oscillates according to the oscillation of the displacement from the equilibrium position at the beginning of the spring.
A sound source fluctuates the same as the compressions of the rings at the beginning of the spring.
The positions of the compression and the rarefaction on the spring do not change.
A coil spring can only oscillate longitudinally.
