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.
Identify all that apply. 1  A sound wave is a mechanical wave. 2  A sound wave is a means of transporting energy without transporting matter. 3  Sound can travel through a vacuum. 4  A sound wave is a pressure wave; they can be thought of as fluctuations in pressure with respect to time.  A sound wave is a transverse wave.
