The displacement of the medium in a sound wave is given by the equation y 1 =Acos(ax+bt) where A,a & b are positive constants. The wave is reflected by an obstacle situated at x=0. The intensity of the reflected wave is 0.64 times that if the incident wave. (a) What are the wavelength and frequency of the incident wave ? (b) Write the equation for the reflected wave. (c) In the resultant wave formed after reflection, find the minimum value of the particle speed in the medium?
