The above image shows a tube of length L which is closed at one end and open on the other side. Based on our discussions above we saw that sound waves (which are longitudinal waves of air molecules) also form standing waves inside a tube. When standing waves form in a tube as shown above, it can have several patterns: First harmonic is the pattern that has the least number of nodes and anti-nodes possible (1 node and 1 anti-node for the sound tube). Second harmonic is the pattern having the next higher number of nodes and anti-nodes (2 nodes and 2 anti-nodes for the sound tube).

Two radio antennas separated by d = 302 m, as shown in the figure below, simultaneously broadcast identical signals at the same wavelength. A car travels due north along a straight line at position x = 1,040 m from the center point between the antennas, and its radio receives the signals. Hint: Do not use the small-angle approximation in this problem. (a) If the car is at the position of the second maximum after that at point O when it has traveled a distance of y = 400 m northward, what is the wavelength of the signals? m (b) How much farther must the car travel from this position to encounter the next minimum in reception?

The two sources S1 and S2 shown in Fig. emit waves ofthe same wavelength λ and are in phase with each other. Suppose S1 isa weaker source, so that the waves emitted by S1 have half the amplitude of the waves emitted by S2. How would this affect the positions of the antinodal lines and nodal lines? Would there be total reinforcement at points on the antinodal curves? Would there be total cancellation at points on the nodal curves? Explain your answers.
