1. Unlike in gases and liquids, sound waves travelling through a solid can propagate as which type(s) of wave?

Longitudinal waves only, exactly as in gases and liquids

Transverse waves only

Both longitudinal and transverse waves

Neither longitudinal nor transverse waves

Solids can resist both compression and shear, so sound can travel through a solid as either a longitudinal or a transverse wave. Gases and liquids resist only compression, so they carry only longitudinal sound waves.
