a. Draw the line showing the third nodal line to the left of the perpendicular bisector. b. What kind of interference is occurring at the location of the square shown to the right of the perpendicular bisector? C. C) How many nodal lines will there be including all lines to the left and the right of the perpendicular bisector? d. d) In the diagram above, the distance between P and S, is 12.0 cm. The distance between P and S, is 9.0 cm. Using the equation PS, - P.S, = (x- -) , determine the wavelength. e. If the speed of the waves is 5.0 cm/s, what must be the frequency?

The physics of wave interference in a ripple rank. The following diagram shows the pattern produced when two sources, 51 and 82. are vibrating in phase at the same frequency in a ripple tank. The solid lines represent crests and the dashed lines represent troughs
