Set 11 Problem 2 The pressure variation in a sound wave is given by AP = 0.0022 sin(1.12 x - 5210 t), where AP is in pascals, x in meters, and t in seconds. Determine a. the wavelength, 15 m abc sin(x) Ox10 Submit Reset b. the frequency, O 5 7 O. f = HZ abc in(x) OX10' Submit Reset c. the speed, m/s abc sin(x) 1x10 Submit Resetc.1he speed, cl. the displacement amplitude of the wave. Assume the denstty of the medium to be 9 = 2700 kglm3. What is the relationship between Lhe pressure amplitude and the displacement amplitude of a sound wave? See Section 16-2. x
