Which example would contain only longitudinal waves? 

a crowd doing the wave at a sporting event 
an ultrasound that transmits soundwaves
the waves formed by the ocean
playing the guitar strings

GPT-5 mini · Answer

An ultrasound that transmits soundwaves.

Reason: Sound in fluids (and air) is a compressional (longitudinal) wave. The crowd “wave” is transverse (people move perpendicular to the wave travel), ocean surface waves are mixed/orbital (both transverse and longitudinal components), and guitar strings mainly support transverse waves.
