PPT-Sound Wave Properties Sound

Sound is a longitudinal Mechanicalwave caused by a vibrating object Molecules collide producing sound Examples Vocal chords guitar or piano strings tuning fork etc Longitudinal Wave. Speed of a Wave on a String. What affects the speed of a . wave on a string?. The properties of the medium through which the wave travels determine the speed of the wave.. If the medium changes, the speed of the wave changes.. 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. Tine . Gulbrandsen. Wahab. . Hanif. . Pure Tones are Very Rare in Nature!. What are real sounds composed of?. Pure Tones are Very Rare in Nature!. What are real sounds composed of?. Virtually all sounds are composed of several (or many) frequencies all going at once. Physics 2415 Lecture 27. Michael Fowler, . UVa. Today’s Topics. Standing waves as sums of traveling waves. Boundary conditions. Longitudinal waves: sound. Amplitude and pressure variations. Strings and pipes. 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. . Section 6.5 Beginning on page 327. Properties. Because logarithms are the inverse functions of the exponential functions, properties of logarithms are similar to properties of exponents. . Product Property:. How do matter and energy interact when waves are generated?. What are the three main types of mechanical waves?. What are properties of waves?. Essential Questions:. Waves. A disturbance that transfers energy from place to place. 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.. 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. Ex. In the ocean, waves travel across but the water only oscillates up and down returning to their original position. . Pulse - a single wave from a disturbance. Ex. Throwing a rock in water (a pulse travels in all directions from the point of contact). Why are we able to see?. Answer: . Because there is light.. And…what is light?. Answer: . Light is a wave.. So…what is a wave?. Answer: . A wave is a disturbance that carries energy from place to place. . Andrew Kennedy. University of Notre Dame. Ning. Lin. Princeton University. NSF CMMI 1314612.
