PPT-Sound Sound waves are longitudinal pressure waves.

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 . Chapter 16. 16.1 The Nature of Waves. A Wave:. Traveling disturbance. Carries energy from place to place. Two Different Types:. Transverse. Longitudinal . Slinky. If the end is jerked up and down, an upward pulse is sent traveling toward the right.. 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. By Rhett Price. Speed of Sound . Speed of sound depends on density. Correlation between speed and density. Not as fast as light speed. Also affected by pressure and temperature. Positive correlation between them. and. Perception of sound. Lecture 8. Pre-reading. : . §16.3. Fourier theorem. Why sine waves?. Any wave shape can be represented as a superposition of normal modes (components). §15.8. Sound as Pressure Wave. 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. In . transverse waves, particles of the medium . move perpendicular . to the direction of the flow . of energy.. In longitudinal waves, particles move parallel . to the . Which of the following waves . requires a material medium through which to travel? . (a) Sound . (b) Television . (c) Radio. (d) X ray. Q1. (a) Sound . Sound is a mechanical wave, transferred through air, or other media, by vibrations passed along through the media. by meaning that it requires a medium through which to travel. . CHAPTER 17.

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.. 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. This Slideshow was developed to accompany the textbook. OpenStax. Physics.

Educational Outreach. Baylor College of Medicine. What Is Energy?. Energy is hard to define because it changes form. Energy causes a change in the condition of matter, or state changes (such as burning a candle). Or it also can mean movement (such as a vibration or change in physical location). .
