A sound wave having a frequency of 266 Hz travels through air at 20 °C. The decibellevel at a distance of 21.3 m from the source is measured to be 77.4 dB. What is themaximum displacement of air molecules at that location? Assume the density of air is1.20 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 bethe number 0.1877.13

A sound has a high pitch and a low volume. What is probably true of this sound wave? Your answer: It has a high frequency, and the amplitude is low because the source is far away. It has a high frequency, and the amplitude is low because close to the observer. It has a low frequency, and the amplitude is low because the source is far away. It has a low frequency, and the amplitude is low because close to the observer.
