Resonance The pendulum Springs Harmonic motion Mechanical waves Sound waves Musical instruments Tacoma Narrows Bridge November 7 1940 httpswwwyoutubecomwatchvnFzu6CNtqec 1 Tacoma Narrows Bridge Collapse. 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.. 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. 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. 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. . .

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 . Introduction. Most mechanical devices such as fans, pumps, etc. produce vibration.. Vibration is easily transmitted through solid materials and may ‘appear’ elsewhere producing troublesome vibration and/or noise.. 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. 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. A wave is a vibration. That travels from place to place. 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. Periodic Motion. Motion that repeats in a regular cycle is called . periodic motion. . . The revolution of a planet about its sun is an example of periodic motion. The highly reproducible period (T) of a planet is also called its year..
