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.
What Is Sound? Sound is a pressure wave which is created by a vibrating object. This vibrations set particles in the sur-rounding medium (typical air) in vibrational motion, thus transporting energy through the medium. Since the particles are moving in parallel direction to the wave movement, the sound wave is referred to as a longitudinal wave. The result of longitudinal waves is the creation of compressions and rarefactions within the air. The alternating configuration of C and R of particles is described by the graph of a sine wave (C~crests, R~troughs) The speed of a sound pressure wave in air is 331.5+0.6T c m/s , T c temperature in Celsius The particles do not move down the way with the wave but osciallate back and forth about their individual equilibrium position.
