'HONORS PHYSICS CH. 14 WAVE PRACTICE PROBLEMS 1. The period of a shudder is 0. 0300 seconds. It travels at a pep pill of 10. 0 m/s. study the oftenness and the joltlength. 2. A loop having a wavelength of 4. 0 meters and an amplitude of 2. 5 meters travels a blank of 24 meters in 8. 0 seconds. take the frequency and the period of the wave. 3. opus hiking by means of a canyon, Noah Formula lets out a scream. An echo (reflection of the scream finish up a nearby canyon wall) is heard 0. 82 seconds after the scream.The make haste of the sound wave in air is 342 m/s. numerate the distance from Noah to the nearby canyon wall. 4. mac and Tosh atomic number 18 resting on crystallize of the water supply near the end of the share when Mac creates a surface wave. The wave travels the length of the pool and back in 25 seconds. The pool is 25 meters long. Determine the speed of the wave. 5. An automatic focus television photographic camera is able to focus on fair games by use of an ultrasonic sound wave. The camera sends out sound waves that reflect off distant objects and return to the camera.A sensor detects the clock it takes for the waves to return and then determines the distance an object is from the camera. The camera lens then focuses at that distance. Now thats a smart camera! In a subsequent life, you world power concord to be a camera; so try this problem for give: If a sound wave (speed = 340 m/s) returns to the camera 0. 150 seconds after sledding the camera, then how farther away is the object? 6. Find the wavelength of a 680-Hz tone in air, where the wave speed is 340 m/s. 7. hypothecate a hiker camping in the mountains.Just before going to sleep he yells, â€Å"WAKE UP,” and the sound echoes off the close mountain, returning 8 h later. How far away is that mountain? 8. Harriet is told by her concern that her heart rate is 70. 0 overcome per minute. If Harriet’s average blood flow in the aorta during systole i s 1. 5 x 10 -2 m/s, what is the wavelength of the waves of blood in Harriet’s aorta, created by her beating heart? 9. While flying to Tucson, Connie’s plane experiences turmoil that causes the coffee in her cup to oscillate back and forth 4 multiplication each second.If the waves of coffee have a wavelength of 0. 1 m, what is the speed of a wave moving through the coffee? 10. Danielle is move her twin Dexter on a swing that hangs from a tree appendage by 2. 0-m-long ropes. With what frequency will Danielle have to push Dexter when he swings? 11. In California, Clay is surfing on a wave that propels him toward the beach with a speed of 5. 0 m/s. The wave crests are each 20. m apart. A. What is the frequency of the water wave? B. What is the period?\r\n'
