- Two sound speakers are separated by a distance d, each sounding a frequency f. An observer stands at one speaker and walks in a straight line a distance x, perpendicular to the the two speakers, until he comes to the first maximum intensity of sound. The speed of sound is v. How far is he from the speaker?A progressive wave travelling in the x-direction is represented by the following equation: ?=?sin(??−??)y=Asin(Bt−Cx). Given that parameters ?A, ?B and ?C are given in SI units calculate the velocity of the wave for ?=50A=50 , ?=B= 2058 and ?=C= 30.Problem 2Given: A wave of 0.3 m wave height and period 1.3 seconds is generated in a wave tank.
