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 endin opposite directions. A sound technician uses a whistle and generates sound waves with a frequency of 242 Hz. The waves travel in opposite directions in a band room, arereflected by end walls, and return. The band room is 44.0 m long and the whistle is located 14.0 m from one end. What is the phase difference (in degrees) between thereflected waves when they meet at the source of the sound? The speed of sound in air is 343 m/s.

A standing wave pattern with 5 nodes is created in a string of length 1.2 m by using waves of frequency 101.0 Hz. What is the speed of the waves in m/s? Answer:
Deep underwater, a sub moves through still water at a speed of 23 m/s. The sub sends out a 910 Hz sonar wave towards an underwater mountain. The wave reflects off the mountain and the sub detects the reflected wave. (The speed of sound in water is 1482 m/s.) Hint: this problem requires two parts. The sub is the source for the initial wave. The frequency does not change when the wave reflects from the mountain. For the reflected wave, the sub is the detector. What frequency does the sub detect for the reflected wave?

A cylinder completely filled with an unknown liquid has a radius of 1.50 cm, a length of 64.0 cm, and a mass of 357 g. An engineer performs an experiment to measure the speed of sound in the liquid. A small speaker emits a sound pulse at one end of the cylinder, which travels through the liquid and is detected by a microphone attached at the other end. The elapsed time between emission of the sound pulse and its detection by the microphone is measured by an electronic circuit to be 5.90 x 10-4 s. What the bulk modulus (in Pa) of the liquid in the cylinder? 3714 x What is the speed of sound in the material? How is it related to the bulk modulus and density of the material? What is the volume of a cylinder? Be careful with units in your calculations. Pa Need Help? Read It Submit Answer

1. (a) What is the intensity in w/m of a laser beam used to burn away cancerous tissue that, when 90.0% absorbed, puts 540 J of energy into a circular spot 2.2 mm in diameter in 1.5 s? Hint: The laser is a collimated beam of light and does not produce a spherical wave. w/m? (b) Reflect on how this intensity compares to the average intensity of sunlight (about 1W/m) and the implications that would have if the laser beam entered your eye. Note how your answer depends on the time duration of the exposure. The intensity of a laser is about damaging if they enter your eye. times that of the sun, so clearly lasers can be very
