PPT-Sound Waves Sound is a Longitudinal

Wave particles vibrate parallel to the direction of the motion of the wave Terminology Compressions areas where particles come closer together Rarefactions regions where particles are further apart. WAves. A wiggle in time is a vibration. .. A wiggle in space and time is a wave.. A vibration can exist in one location, a wave cannot. A wave must travel from one place to another.. Vibration of a Pendulum. Describe what you notice in the following situations:. The drummers from the marching band are right by you and are playing loudly.. You are sitting right next the speakers playing loud music.. Someone drives by in their car with the bass turned up.. Section 8.2 / 8.3. 8.2 Question 1.

Sound waves are made up of a series of regions of high and . low pressure. . The areas of high pressure are called . compressions. . The . areas . of low pressure are called . rarefactions.. Wave energy travels through the material. But a particular piece . An old riddle ….. If a tree falls in a forest, and no one hears it, does the tree make a sound?. What is “sound”?. Sound Waves. To a scientist, a tree makes a sound whether someone hears it or not.. Producing and Detecting sound. What is sound?. The sound you hear is sound waves that can only travel through matter.. Sound waves are longitudinal waves. . Sources of sound. Every sound comes from a vibration, which is the energy that the wave uses to carry the sound..
