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 . More Properties of Sound. Resonance. Definition: when a force is applied to an object in repeated motion at exactly the natural frequency, an increase in amplitude occurs.. Important points: force applied AT the natural frequency!. 5.1.9. You and I are standing next to each other, listening to the exact same steady sound. . Our ears are identical. . You listen for TWICE as long as I do. How does the (average) power compare? (Please average ONLY over the time that the individual is listening!). Frequency. Medium. Vibration. Sound Waves. Compression . Rarefaction. What is a sound wave?. What section are seen in a sound wave?. amplitude. a. mplitude. :. . is the maximum distance a particle travels from rest. . 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 . Sound waves carry energy that can be used to do work, like forcing the eardrum to vibrate.. The energy can be great enough to cause damage to windows and buildings (sonic boom). Sound Intensity. The amount of energy transported per second by a sound wave is the . Wave Properties. There are 6 main properties, or interactions, of waves that occur when a wave comes in contact with another wave , or a boundary. . The 6 Interactions of waves are. Interference. Diffraction. 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. .
