1. A group of curious 9B students are listening to sound generated by standing waves in a tube of air. However, they cannot see the tube itself, so they don't know if both ends of the tube are open or if only one end of the tube is open (and the other closed). They observe a standing wave in which the distance from node to adjacent anti-node is 0.6 m. The frequency is increased until the next harmonic is reached. The new distance from node to adjacent anti-node is 0.4 m, and the frequency increased by 1000 Hz. a) Are both ends of the tube open or only one end? b) Determine which harmonics are being played and determine the length of the tube. c) Now consider a different tube with end conditions different than what you determined in part a. (For example, if you determined both ends were open in part a, then this new tube has one open end and one closed end). What should the length of this tube be such that its fundamental frequency is the same as the tube you considered in parts a and b?

As shown in the figure below, a string attached to a vertical wall passes over a pulley at the end of a horizontal rod, and supports a sphere. The horizontal rod has a length L = 0.320 m, the mass of the sphere is M = 1.20 kg, the string makes an angle ? = 38.0° with the rod, and, when the string is plucked, the fundamental frequency of standing waves in the portion of the string above the rod is f = 70.0 Hz. Determine the mass of the portion of the string above the rod (in g). Answer:___________ g

Diego is standing 7.0 m North of a pair of adjacent speakerswhich are facing him. The speakers are coherently producing afrequency of 686 Hz. Diego’s friend, Shalanda, is going to moveone of the speakers directly East. How far away from the stationary speaker should Shaland move the other one such thatthe sound cancels out where Diego is standing? Find the minimum amount it should be moved. Hint: what is the conditionfor coherent waves to cancel?
The wave patterns of various delta w and delta k values are not same , even though the group velocity Vg is 1 for each wave pattern( due to delta w and delta k being equal to each other ) . Why are not all the wave patterns same ?
A sinusoidal wave on a string is described by the wave function ?(?,?) = 0.02 sin(30? − 400?) (SI units). If the string’s linear mass density is ? = 0.005 kg/m, then the transmitted power is:
A wire of length L₁ = 30 cm has one end fixed and the other end welded to another wire, whose linear density of mass is 4 times smaller. The second wire passes through a pulley and a mass of 10 kg is suspended by its other end. The distance L₂ between the weld point and the pulley is 80 cm. A stationary wave is produced in the composite wire, whose ends at the left wall and the pulley remain fixed.
