Concept explainers
An airport neighborhood is concerned about the basing of the new F-35 jet fighter. They’ve got the data below for the sound intensity level measured at different distances from the plane as it takes off. They’d like to know the total sound power emitted by the plane. As a physics student, you’re called to help. First, convert the sound intensity levels to actual intensity. Then find a quantity which, when you plot intensity against it, should give a straight line. Make your plot, determine the best-fit line, and use its slope to report the total sound power.
Distance (m) | 1000 | 1200 | 1500 | 2000 | 3000 | 4000 |
Sound intensity level (dB) | 80.7 | 79.4 | 76.9 | 74.2 | 71.6 | 68.8 |

Calculate the displacement amplitude of the wave at a frequency of 10.0 kHz.arrow_forwardIn Figure OQ14.3, a sound wave of wavelength 0.8 m divides into two equal parts that recombine to interfere constructively, with the original difference between their path lengths being |r2 − r1| = 0.8 m. Rank the following situations according to the intensity of sound at the receiver from the highest to the lowest. Assume the tube walls absorb no sound energy. Give equal ranks to situations in which the intensity is equal. (a) From its original position, the sliding section is moved out by 0.1 m. (b) Next it slides out an additional 0.1 m.
