A popular distraction in large crowds at sporting events since the 1980s is the "wave." People in one section quickly stand up and raise their arms and then sit down; people in the neighboring sections follow suit in succession, resulting in a visible pattern in the crowd that travels around the stadium. Which of the two types of waves is this? Compared to the waves described in this chapter, how is the stadium wave different?

- What is the difference between propagation speed and the frequency of a mechanical wave? Does one or both affect wavelength? If so, how?arrow_forwardCheck Your Understanding Describe how noise-canceling headphones differ from standard headphones used to block outside sounds.arrow_forwardA microphone receiving a pure sound tone feeds an oscilloscope, producing a wave on its screen. If the sound intensity is originally 2.00105W/m2 , but is turned up until the amplitude increases by 30.0% , what is the new intensity?arrow_forward
- Check Your Understanding The equations for the wavelengths and the frequencies of the modes of a wave produced on a string: n=2nLn=1,2,3,4,5...andn=nv2L=nf1n=1,2,3,4,5... were derived by considering a wave on a string where there were symmetric boundary conditions of a node at each end. These modes resulted from two sinusoidal waves with identical characteristics except they were moving in opposite directions, confined to a region L with nodes required at both ends.Will the same equations work if there were symmetric boundary conditions with antinodes at each end? What would the normal modes look like for a medium that was free to oscillate on each end? Don’t worry for now if you cannot imagine such a medium, just consider two sinusoidal wave functions in a region of length L, with antinodes on each end.arrow_forwardHow do sound vibrations of atoms differ from thermal motion?arrow_forwardCheck Your Understanding Describe a situation in your life when you might rely on the Doppler shift to help you either while driving a car or walking near traffic.arrow_forward
- When poked by a spear, an operatic soprano lets out a 1200-Hz shriek. What is its wavelength if the speed of sound is 345 m/s?arrow_forwardConsider the superposition of three wave functions y(x,t)=3.00cmsin(2m1x3s1t) , y(x,t)=3.00cmsin(6m1x+3s1t) , and y(x,t)=3.00cmsin(2m1x4s1t) . What is the height of the resulting wave at position x=3.00 m at time t=10.0 s?arrow_forwardConsider a wave produced on a stretched spring by holding one end and shaking it up and down. Does the wavelength depend on the distance you move your hand up and down?arrow_forward
- Check Your Understanding Describe how amplitude is related to the loudness of a sound.arrow_forwardEarly Doppler shift experiments were conducted using a band playing music on a train. A trumpet player on a moving railroad flatcar plays a 320-Hz note. The sound waves heard by a stationary observer on a train platform hears a frequency of 350 Hz. What is the flatcar’s speed in mph? The temperature of the air is TC=22C .arrow_forwardHow far should you stand away from a sound source that generates and 85-W power to cause damage to your ears?arrow_forward
