1. In a large water tank two sources (Si and S2) are in phase with a common frequency separated by 6.0 cm. The wavelength of the waves in the water is 2.0 cm. a) A nodal point P: (on the second nodal line) is 0.24 m from Si, how far is this point from the other source? b) The nodal point P: (located on the first nodal line), is located 0.120 m from the perpendicular bisector of the two sources. How far in the nodal point from the midpoint of the two sources? c) Find the angle to distant points of the 2nd nodal line.

(Question 22) Answer step to step the following question: Two speakers on the Ox axis emit sound waves from the same direction along the axis. Speaker 2 is 2.0 m behind speaker 1. The two speakers are connected to the same signal generator, which oscillates the 340 Hz, but the wire connecting it to speaker 1 goes through a box containing a electronic device that delays the signal by 1.47 ms. Along the Ox axis. To along the Ox axis, the interference is totally constructive, totally destructive or something in between? (Consider v= 340 m/s) Justify your asnwer.
