Question
Two loudspeakers emit sound waves along the x-axis. A listener in front of both speakers hears a maximum sound intensity when speaker 2 is at the origin and speaker 1 is at x = 0.510 m . If speaker 1 is slowly moved forward, the sound intensity decreases and then increases, reaching another maximum when speaker 1 is at x = 0.870 m .
What is the phase difference between the speakers?

- Two motors sitting near each other in a factory at slightly different rates. One runs at 805.0 rpm and the other at 775.0 rpm. You hear the combined sound intensity from the motors increase and then decrease periodically due to wave interference. What is the period of beats in seconds?arrow_forwardA cable with a linear density of u = 0.210 kg/m is hung from telephone poles. The tension in the cable is 550.00 N. The distance between poles is 24 meters. The wind blows across the line, çausing the cable resonate. A standing waves pattern is produced that has 3.0 wavelengthš between the two poles. The air temperature is T'= 24°C. What are the frequency and wavelength of the hum? A =arrow_forwardA sound wave having a frequency of 266 Hz travels through air at 20 °C. The decibel level at a distance of 21.3 m from the source is measured to be 77.4 dB. What is the maximum displacement of air molecules at that location? Assume the density of air is 1.20 kg/m³ and that the source produces spherical wave fronts. Express the displacement as a number having the units of mirco meters. 1 micro meter = 1 x 10-6 m. For example, If your calculated answer were 1.873 x 10-7 m, your entry would be the number 0.187 7.13arrow_forward
- The two successive harmonic frequencies of a 0.45 m long sound pipe are 929 Hz and 1300 Hz. a) Is the pipe open at both ends or only at one end? b) What is the propagation speed of the wave?arrow_forwardDolphins of the open ocean are classified as Type II Odontocetes (toothed whales). These animals use ultrasonic "clicks" with a frequency of about 55 kHz to navigate and find prey. Suppose a dolphin sends out a series of clicks that are reflected back from the bottom of the ocean 90 m below. How much time elapses before the dolphin hears the echoes of the clicks? (The speed of sound in seawater is approximately 1530 m/s.) What is the wavelength of 55 kHz sound in the ocean?arrow_forwardDetermine the wavelength of the sound for 24 Hz. Determine the wavelength of the sound for 23 kHz.arrow_forward
- If a tuba is 5.3 m away, what is the intensity of the sound wave produced by a tuba that has a power output of 0.29 W? Assume the sound waves are spherical. 3.31 x 10-4 W/m2 8.21 x 10-4 W/m2 9.21 x 10-3 W/m2 4.32 x 10-5 W/m2arrow_forwardTwo loudspeakers emit sound waves of the same frequency along the x-axis. The amplitude of each wave is a. The sound intensity is minimum where speaker 2 is 10cm behind speaker 1. The intensity increases as speaker 2 is moved forward and first reaches minimum, with amplitude 2a, when it is 30cm in front of speaker 1. a. what is the wavelength of the soundarrow_forward1arrow_forward
