QuarkGluonPlasma Based on 09052097 Neda Sadooghi Department of Physics Sharif University of Technology TehranIran MIDEAST 2009 QCD Phase Diagram Main Goals Physics of the Early Universe. 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.. 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.. alternative. GAS MIXTURES. Fernando J. Pérez Sanz. Universidad de Valladolid. Spain. Motivation of the study. Depleting of fossil fuels reservoirs.. Increasing prices of fuels. Environmental problems . What is . Mach One?. Did you hear that SOUND?. Sound is a form of energy . that travels in . waves.. What makes Sound?. Vibration: back and forth motion. There can not be sound if there is not any vibration. Speed of a wave on a string:. T is tension sometimes listed as F for force on string.. m. is the density of the string mass/length. and . f . = . v. /. l. If wavelength is fixed, how does frequency change if v goes up?. Audible (. adj.) . able to be heard. Oscillate . (v.) . to sway from one side to another. Dissonance (. n.) . lack or harmony or consistency. Undulate (. v.) . to move in waves. SAT VOCAB TWO. Now that we are through with waves, we are moving onto the topic of sound. Sound waves are waves that are . What is sound?. Sound. is a form of energy that can be heard. and travels in waves.. When matter . vibrates. or moves back and forth. very quickly, a sound is made.. Sound waves can travel through solids, liquids, or gases.. An old riddle ….. If a tree falls in a forest, and no one hears it, does the tree make a sound?. What is “sound”?. Sound Waves. To a scientist, a tree makes a sound whether someone hears it or not.. Sound waves are longitudinal!. Sound can be explained by understanding:. Speed. Intensity. . and loudness. Frequency and pitch. Most people hear sound between the frequency of 20Hz and 20,000Hz. . Anatomy of Sound. CAPT Joe Brenner. . Outline. Objectives:. Identify major milestones in Ocean Acoustics. Describe the process of ocean sound propagation. Discuss sound attenuation/refraction in the ocean. Listen to applications of ocean sound . 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.. Sound is a . longitudinal. . (Mechanical)wave caused by a . vibrating. object. Molecules . collide. , producing sound. Examples: . Vocal chords. , guitar or piano strings, tuning fork, etc.. . Longitudinal Wave. Benjamin Hardy, . Bowling Green State University. . Joseph .
