If you haven't had your teeth cleaned in a long time or have had a lot of problems with your teeth, you may have to get a procedure called scaling and root planing, which involves cleaning the root surfaces of your teeth, which is more expensive than a routine visit.
The key background to this question is the nature of sound waves and light waves. Youâre right in that sound waves are a vibration traveling through an object, including condensed things like solids and liquids. In solids, those waves can consist of either alternating compressed and stretched regions, or regions wiggling sideways, compared to the direction the wave is traveling.
Sound can also mean a body of water, like a bay or channel. We can define a sound wave as a disturbance which travels through some medium. Sound is the term to describe what is heard when sound waves pass through a medium to the ear. All sounds are made by vibrations of molecules through which the sound travels. For instance, when a drum or a cymbal is struck, the object vibrates. These vibrations make air molecules move.
