Correct Answer: Either longitudinal or transverse
Solution : The correct option is Either longitudinal or transverse.
In solids, sound can travel as both longitudinal waves and transverse waves . Longitudinal sound waves involve oscillations of pressure deviations from the baseline pressure, creating regions of compression, and rarefaction. Meanwhile, transverse waves in solids consist of alternating shear stress occurring perpendicular to the direction of propagation.
