You shout “hello” into an echo chamber that is 250 m long. Assuming that the speed of sound is 340 m/s , how long will it take for you to hear your echo? We are going to pretend that there is no damping of the sound and this echo chamber is perfectly reflective in only 1- dimension ( Horizontally). Hint: how far does the wave travel before it reaches you?

A loudspeaker having a diaphragm that vibrates at 1250 Hz is traveling at 80 m/s directly toward a pair of holes in a very large wall in a region for which the speed of sound is 344 m/s. You observe that the sound coming through the openings first cancels at 11.4 deg with respect to the original direction of the speaker when observed far from the wall. How far apart are the two openings? What angles would the sound first cancel if the source stopped moving?
What is the wavelength of a wave moving through diamond (v = 12000 m/s) with a frequency of 15000 Hz?
Despite the availability of music in digital form, the compact disc, or CD, remains a popular format for music and data. On a CD (as shown), audio information is stored digitally in a series of pits and flat areas on the surface of the disc. The alternations between pits and flat areas on the surface represent binary ones and zeros to be read by the CD player and converted back to sound waves. The pits and flat areas are detected by a system consisting of a laser and lenses. The length of a string of ones and zeros representing one piece of information is the same everywhere on the disc, whether the information is near the center of the disc or near its outer edge. So that this length of ones and zeros always passes by the laser–lens system in the same time interval, the tangential speed of the disc surface at the location of the lens must be constant. According to Equation 10.10, the angular speed must therefore vary as the laser–lens system moves radially along the disc. In a typical…

Two loudspeakers are placed above and below each other, as in the figure, and driven by the same spice at a frequency of 5.60* 10^2 Hz. An observer is in front of the speakers at point O, at the same distance from each speaker. What max vertical distance upward should the top speaker be moved to create destructive interference at point O? ( assume spread of sound is 343m/s)
Water waves with an amplitude of 0.80cm and a wavelength of 2.5cm go through two openings in a barrier. Each opening is 1.2cm wide, and the openings are seperated by 12.0cm(center to center). Find the angles of the lines along which the waves constructively interfere.
A riverside warehouse has several small doors facing the river. Two of these doors are open as shown in Figure P27.17. The walls of the warehouse are lined with sound-absorbing material. Two people stand at a distance L = 150 in from the wall with the open doors. Person A stands along a line passing through the midpoint between the open doors, and person B stands a distance y = 20 m to his side. A boat o the river sounds its horn. To person A, the sound is loud and clear. To person B, the sound is barely audible. The principal wavelength of the sound waves is 5.00 m. Assuming person B is at the position of the first minimum, determine the distance d between the doors, center to center.
A physicist drives through a stop light. When he is pulled over, he tells the police officer that the Doppler shift made the red light of wavelength 650 nm appear green to him, with a wavelength of 520 nm. The police officer writes out a traffic citation for speeding. How fast was the physicist traveling, according to his own testimony?
Suppose that the separation between two speakers A and B is 6.90 m and the speakers are vibrating in-phase. They are playing identical 135-Hz tones and the speed of sound is 343 m/s. An observer is seated at a position directly facing speaker B in such a way that his line of sight extending to B is perpendicular to the imaginary line between A and B. What is the largest possible distance between speaker B and the observer, such that he observes destructive interference?
