Section 8.5. Key Terms. Audible Sound Waves. Infrasonic Wave. Ultrasonic Wave. Echo. Mach Number (. M. ). Pressure (. p. ). Sound Intensity. Decibel (dB). Categories of Sound Waves. Sound waves fall into three categories covering different ranges of frequencies.. 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. Students . will explore the wave nature of sound and electromagnetic radiation. . Identify . the characteristics of electromagnetic and . mechanical waves. . . b. Describe how the behavior of light waves . the Electromagnetic Spectrum. Waves. All waves carry … ENERGY!!!. Electromagnetic Waves (light) . Light waves are . transverse. waves. Electromagnetic. Radiation. Energy emitted from the . S8P4. . Students will explore the wave nature of sound and electromagnetic radiation. . Identify . the characteristics of electromagnetic and . mechanical waves. . . b. Describe how the behavior of light 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 . 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.. 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.
