PPT-Sound Waves

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 . Doppler Effect. ~apparent change in frequency of a wave due to the motion of the source of the wave.. If the object is moving towards the observer the frequency will appear to increase. If the object is moving away from the observer the frequency will appear to decrease. S8P4. .

To describe mechanical waves.. To study superposition, standing waves and sound.. To present sound as a standing longitudinal wave.. To see that waves will interfere (add constructively and destructively).. 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 .

Crest . – . the highest part of a transverse wave.. Remain as quiet as you can for 1 minute.. I will tell you when to begin, and when to stop.. In the margin of your paper, write down all of the different sounds that you hear in the environment around you.. Sound Chapter 12 Sound hunt Remain as quiet as you can for 1 minute. I will tell you when to begin, and when to stop. In the margin of your paper, write down all of the different sounds that you hear in the environment around you. Before the waves are made the particles are same distance apart. While waves moves through the medium the particles . compress. together, then they spread further apart (stretched areas)- . rarefaction.. Mechanical Waves. A mechanical wave is created when a source of energy causes a vibration to travel through a medium.. A mechanical wave is a disturbance in matter that carries energy from one place to another.. 2022-2023 Season. Russ Burleson. geaux15@hotmail.com. . 1. Agenda. Binder Check/Homework review. Mechanical Wave overview. Transverse Waves. Surface Waves. Longitudinal Waves (general). Sound Waves (Longitudinal). Energy is moving, not water. orbital motion. energy is transferred via circular motions. water (and gull) return to original position. the wave form moves forward. Motion decreases with depth. At. a depth of ½ of the wavelength, the motion is not significant..
