Answer»

Sound waves are formed when a VIBRATING object causes the surrounding medium to vibrate. ... As sound waves MOVE through a medium the particles vibrateforwards and backwards. Asound's volume, how loud or SOFT it is, depends on the sound wave. The more energy PUT into making a sound or a sound wave, thelouder it will be.
