PHY 215 Study Guide - Final Guide: Decstation, Bulk Modulus, Angular Frequency
Document Summary
If the pulse reaches a free end, the pulse is reflected, but not inverted. The wave function for a 1-d sin wave travelling to the right can be expressed as y = A is amplitude, k is angular wave number, is angular frequency. If t is period, and is the wavelength, v = If t is period, and is the wavelength, k = If t is period, and is the wavelength, = Power transmitted by a sin wave on a stretched string is p = Sound waves are ______ and travel through a compressible medium with a speed depending on the compressibility and the inertia of that medium. Speed of sound in a medium with bulk modulus b and density is v = sqrt[b/ ] For sinusoidal sound waves, the variation in the displacement is given by s(x,t) = smaxcos(kx- *t) For sinusoidal sound waves, the variation in the pressure from the equilibrium value is p =
