Transverse waves require shear stiffness, i.e., resistance to sideways deformation. Liquids have no shear stiffness, only compressional stiffness.

that'll be a longitudinal mechanical wave. Reason: it's EXACTLY the same as a normal sound wave, a normal sound wave is longitudinal mechanical wave. The difference between ultra sound and normal sound is in the frequency. The frequency of an ultra sound is above 20 000 Hz, which is the rough approximate of human ear's limit of hearing a sound wave, sounds that are higher than 20 000Hz are called ultra sound (or ultrasonic) Note: 20 000 is not an absolute limit, some people may hear up to 22 000Hz, while some others only up to 16 000 Hz. This limit usually decreases as people age.

The transverse mechanical waves do not occur in fluids,
Because the molecules of fluids are closely attached to
each otherAND because of " Surface-Tension ".
