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.
The various properties of electromagnetic waves and sound waves are described below. Sound waves are mechanical waves generated from vibrations within a medium. Sound can exist as longitudinal mechanical waves, which are also known as compression waves. These waves can travel through solid, liquid, gas or plasma media. Sound waves require a medium to travel.
