As a certain sound wave travels through the air, it produces pressure variations (above and below atmospheric pressure) given by AP = 1.26 sin(x - 335´t) in SI units. (Note: Use the following values 1.20 kg/m³. Pressure variations AP are measured relative to atmospheric pressure, 1.013 × 105 Pa.) as needed, unless otherwise specified. The equilibrium density of air is p = (a) Find the amplitude of the pressure variations. 1.26 Pa (b) Find the frequency of the sound wave. 162.5 X Review the general equation for a wave to determine which quantities give the frequency. Hz (c) Find the wavelength in air of the sound wave. 325 X Review the general equation for a wave to determine which quantities give the wavelength. m (d) Find the speed of the sound wave. 2 X Check the units of the expression you used to calculate the speed. m/s Need Help?
