Two waves travelling in the same direction are given by: y1 = 0.2 sin(2rx-20t+p)
and y2 = 0.2 sin(2Ttx-20t), where x and y are in meters and t is in seconds. If the

two waves start at the same moment, then the path difference, Ax,
corresponding to a fully destructive interference is:
A point on the third nodal line from the center of an interference pattern is 40.1 cm from one source and 31.8 cm from the other. The sources are 10.4 cm apart and vibrate in phase at 14.0 Hz. Calculate the wavelength of the waves, in cm.
Two out of phase loudspeakers are some distance apart. A person stands 5.40 m from one speaker and 3.20 m fromthe other. What is the second lowest frequency at which constructive interference will occur? The speed of sound in air is346 m/s.
