Two wave sources, separatedby 6.00 cm, produce waves - in phase - described by y = 4sin(50πx - 120πt)m. (Assume that these are ripples on thesurface of a pond.)
A) What is the speed of these waves? (remember the expressions for kand ω)
B) What will be the resultant disturbance (maximum? minimum? something in between?) at a point Pwhich is 50 cm from one source and 52 cm from the other?
C) Now consider a pointP, on the surface of the water, very near one of these sources. Suppose that a practically weightless cork floats at P. What would be its maximum displacement? What would beits maximum speed?
