2. a) the resultant of two interfering wave of the same wavelength and the frequency is given as y=(14 mm)sin(kx+?t+0.5 rad). one of the interfering waves is y1=(8mm)sin(kx+?t). Calculate the amplitude and phase constant of the other interfering wave. draw and label the appropriate phasor diagram and perform the calculations to obtain this amplitude and phase constant. write the equation of this interfering wave.
b) sound of a single frequency is sent into the system of pipes, one straight, the other consisting of two semi-circular paths of radii 20cm and 30cm. what is the lowest frequency that produces an intensity maximum on the output side?
