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.. 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. 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. 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 . waves_04. 1. flute. clarinet. click for sounds. waves_04: MINDMAP SUMMARY - SOUND WAVES. 2. Sound waves, ultrasound, compressional (longitudinal) waves, pressure, particle displacement, medical imaging, superposition principle, stadning waves in air columns, constructive interference, destructive interference, boundary conditions, pipe – open and closed ends, nodes, antinodes, speed of sound in air, period, frequency, wavelength, propagation constant (wave number), angular frequency, normal modes of vibrations, natural frequencies of vibration, fundamental, harmonics, overtones, harmonic series, frequency spectrum, radian, phase, sinusoidal functions, wind musical instruments, beats, beat frequency, Doppler Effect, Doppler radar, shock waves. 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 . . [3]. resonance . clocks – pendulum . springs . harmonic motion . mechanical waves . sound waves . The periodic wave relation. Wave interference. standing waves. beats. musical instruments. 1. Review. 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.. REMINDER!. DON’T FORGET. TO . STUDY!. . Electromagnetic waves. Mechanical waves. Interference. Reflection. Refraction. Pitch. diagrams. 1. Define . the following words:. Crest . – . the highest part of a transverse wave.. 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. There are many sources of vibration on construction sites and therefore we want to discuss this topic with you today to raise awareness of the health issues it can lead to if not correctly . controlled.. 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.. 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..
