What do we call waves that must travel through a medium?

I found this on Google. You could have done the same and gotten your answer much faster than two hours.

"Waves that transfer energy through a medium are called mechanical waves. Waves that can transfer energy through a vacuum and do not need a medium are electromagnetic waves. Electromagnetic waves are produced by the vibrating charged particles, resulting in changes in electric and magnetic elds.Apr 21, 2020"

Waves that must travel through a medium are called mechanical waves. Mechanical waves require a medium, such as water, air, or solids, to propagate or travel through. Examples of mechanical waves include sound waves, water waves, and seismic waves.

Waves that require a medium to travel through are often referred to as mechanical waves. These waves rely on particles of matter to transfer energy and propagate through a medium like solid, liquid, or gas. Examples of mechanical waves include sound waves, water waves, and seismic waves.
