PPT-Waves and Sound S3 Discrete Physics

Recap What is a wave A wave transfers Energy without transferring Matter There are two types of wave Transverse eg Light Longitudinal eg Sound Vibrations act at right angles perpendicular to the direction of wave travel. 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.. 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.. 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.

Energy is transferred through air (sound). 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. . 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.

Restoring forces can result in oscillatory motion. When linear restoring force is entered on an object displacement from an equilibrium position, the object will undergo a special type of motion called simple harmonic motion (SMH). .
