11. A ripple in a pond and a wave on a string are easily visualized as transverse waves . 12. I question the claim that electron drift through a conductor carrying alternating current is a transverse wave . 13. In solids, mechanical waves can take many forms including longitudinal waves, transverse waves and surface waves. 14. Transverse waves , also known as polarization ", and are not a characteristic of sound waves.15. But an electro-magnetic wave is a kind of progressive wave ( more specifically transverse wave ). 16. Consider a traveling transverse wave ( which may be a pulse ) on a string ( the medium ). 17. I added to the Sound article information that transverse waves are at right angle to the direction of propagation. 18. Acoustic isotropic radiators are possible because sound waves in a gas or liquid are longitudinal waves and not transverse waves . 19. Liquids ( By that I mean Newtonian liquids ) like gasses cannot carry transverse waves ( s-waves ). 20. As transverse waves , S-waves exhibit properties, such as polarization and birefringence, much like other transverse waves.
