A sound wave is modeled with the wave function P = 1.20 Pa sin (k x 6.28 × 10 4 s 1 t) P=1.20Pasin(kx6.28×104s1t) and the sound wave travels in air at a speed
17.1 Sound Waves - University Physics Volume 1 OpenStaxv = k = T. Sound waves can also be modeled in terms of the displacement of the air molecules. The displacement of the air molecules can be modeled using a cosine function:s ( x, t) = s max cos ( k x t + ). s ( x, t) = s max cos ( k x t + ). 17.2. In this equation, s is the displacement and. s max.

Oct 25, 2020 · But sound has important applications beyond hearing. Ultrasound, for example, is not heard but can be employed to form medical images and is also used in treatment. Figure \(\PageIndex{1}\):This glass has been shattered by a high-intensity sound wave of the same frequency as the resonant frequency of the glass.
17.3:Speed of Sound - Physics LibreTextsNov 12, 2020 · For air, \(\gamma\) = 1.4, M = 0.02897 kg/mol, and R = 8.31 J/mol K. If the temperature is T C = 20 °C (T = 293 K), the speed of sound is v = 343 m/s. The equation for the speed of sound in air v = \(\sqrt{\frac{\gamma RT}{M}}\) can be simplified to give the equation for the speed of sound in air as a function of absolute temperature:
17.4 Normal Modes of a Standing Sound Wave - University Figure 17.16 When sound waves are produced by a speaker, they travel at the speed of sound and move out as spherical waves. Here, two speakers produce the same steady tone (frequency). The result is points of high-intensity sound (highlighted), which result from two crests (compression) or two troughs (rarefaction) overlapping.

Figure 17.36 Sound waves from a source that moves faster than the speed of sound spread spherically from the point where they are emitted, but the source moves ahead of each wave. Constructive interference along the lines shown (actually a cone in three dimensions) creates a shock wave called a sonic boom. The faster the speed of the source, the smaller the angle
17.S:Sound (Summary) - Physics LibreTexts17.2:Speed of Sound. The speed of sound depends on the medium and the state of the medium. In a fluid, because the absence of shear forces, sound waves are longitudinal. A solid can support both longitudinal and transverse sound waves.
