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).

The diagram below shows the wave crests for two sources that are totally in phase. For each of the labeled points, determine whether the light intensity (not the wave amplitude) is a minimum or a maximum. B S, Maximum Minimum Neither Submit Answer Tries 0/100

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?

Inteity rty (500nm Question: Explain how your screenshots show the two different types of wave interference - constructive and destructive. Please explain your answer in at least two complete sentences.

What is the difference between a continuous spectrum and a discrete spectrum? O A discrete spectrum is represented by distinct spectral components. A continuous spectrum represents a sound that continues indefinitely. O A discrete spectrum represents a sound that is turned on and off. A discrete spectrum is represented by an area under a curve.
