Mr. Richter. Agenda. Podcast Check. Questions about 13.1 Sound Waves. Upcoming Schedule. Notes:. Intensity and Volume. Decibel levels. Forced Vibrations and Resonance. Upcoming Schedule. 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. Section 8.1. Question 1. Sample . answer:. A . vibration is the cyclical motion of an . object about . an equilibrium point. A wave is the . transfer of . energy through a material due to . vibration. Vibration . Now hear this!. Sound is a form of energy.. Other types of energy we will learn about are heat and light.. What is sound?. Science Benchmark. Heat, light, and sound are all forms of energy... Sound is created by vibration and cannot travel through a vacuum. Pitch is determined by the vibration rate of the sound source. Waves-3. resonance . clocks – pendulum . springs . harmonic motion . mechanical waves . sound waves . The periodic wave relation.

(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. . .

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 . Use your knowledge of waves & physics to answer the question.. Sound. Longitudinal wave phenomenon that consists of successive compressions and rarefactions of the medium through which the wave travels. . 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.

Thus it is two motions each with its own direction. The . Vibration. : a SHM. The . Propagation. ; its motion from place to place. Together they from a wave. 2022-2023 Season.
