10. The figure shows two loudspeakers (A) and (B), and a point (C) where a listener is positioned. The speakers vibrate out of phase and are playing a 71.0 Hz tone. The speed of sound is 336 m/s. The listener at point (C) hears the second destructive interference (not counting the point at infinity) at a distance 4.50 m as measured from speaker (A). What is the separation (d) between the two speakers? m

For testing purposes, a musical instrument manufacturing company creates a device so that when you blow into one end with your instrument, sound comes out the other end in opposite directions. A sound technician uses a whistle and generates sound waves with a frequency of 280 Hz. The waves travel in opposite directions in a sound studio, are reflected by end walls, and return. The studio is 43.0 m long and the whistle is located 14.0 m from one end. What is the phase difference (in degrees) between the reflected waves when they meet at the source of the sound? The speed of sound in air is 343 m/s. 17044.898X See if you can determine the path difference and the wavelength, and then express the path difference in terms of the wavelength. What part of the path difference is of interest to us when finding the phase difference? How is this part of the path difference related to the phase difference? • Need Help? Read It
Consider the speaker set-up in the previous question. Each speaker emits a frequency of 6.6·102 Hz in phase with the other. The listener is seated directly in front of one speaker, 1.6 m away. The speakers are 2.4 m away from each other. How many extra wavelengths are needed for sound to get from speaker 2 to the listener? Take the speed of sound in air to be 3.4·102 m/s.
X/10. It is √gd, so A water wave is a shallow-water wave if the water depth d is less than shown in hydrodynamics that the speed of a shallow-water wave is v = waves slow down as they move into shallower water. Ocean waves, with wavelengths of typically 100 m, are shallow-water waves when the water depth is less than 10 m. Consider a beach where the depth increases linearly with distance from the shore until reaching a depth of 5.4 m at a distance of 100 m. Part A How long does it take a wave to move the last 100 m to the shore? Assume that the waves are so small that they don't break before reaching the shore. Express your answer to two significant figures and include the appropriate units. At = Value Units ?
