Vibration in a stretched spring cannot be polarized because they are
stationary waves
transverse waves
longitudinal waves
mechanical waves
Correct answer is C
In longitudinal waves, such as sound waves in a liquid or gas, the displacement of the particles in the oscillation is always in the direction of propagation, so these waves do not exhibit polarization.
