Third, sound is a vibration that travels through a medium, like a gas, a liquid or a solid object. A sound's source is an object that moves or changes shape very rapidly. For example, if you strike a bell, the bell vibrates in the air. As one side of the bell moves out, it pushes the air molecules next to it, increasing the pressure in that region of the air. This area of higher pressure is a compression. As the side of the bell moves back in, it pulls the molecules apart, creating a lower-pressure region called a rarefaction. The bell then repeats the process, creating a repeating series of compressions and rarefactions. Each repetition is one wavelength of the sound wave. The sound wave travels as the moving molecules push. Pull the molecules around them. Each molecule moves the one next to it in turn. Without this movement of molecules, the sound could not travel, which is why there is no sound in a vacuum.|Ah, the thought of a massage has you relaxing already, but which one should you go with? You have a headache, your back is killing you and your neck cracks every time you look up. Boy, do you need a little pampering. A massage may be just the thing to knock out the kinks and get your muscles feeling supple and relaxed again. But which massage should you choose? The term "massage" can be a little confusing. You can get a Swedish-style massage to loosen tired muscles, or indulge in a relaxation massage that's as much a spiritual experience as a physical one. You can also get a targeted massage, like a deep tissue that will reduce muscle stress in a specific area, such as your shoulders or lower back. Some of these techniques are more spa-style treatments while others may enlist the aid of a physical therapist or be performed in a chiropractor's office as part of an overall wellness program.
