An observer detects an apparent change in the frequency of sound waves produced by an airplane passing overhead . This phenomenon illustrates:

A ) the Doppler effect

B ) the refraction of sound waves

C ) an increase in wave amplitude

D ) an increase in wave intensity

Expert Solution

Waves are not a motion of mass, but they are able to transfer energy without the transfer of mass. There are many types of waves with different speeds and shapes.

The Doppler effect occurs with all types off waves, including light. It is a result of relative motion between a source of waves and an observer. As the distance between the source and the observer decreases, then the frequency of the source from the observer perspective would increase. As the distance increases, then the apparent frequency is decreased.

This phenomenon is shown in the real world with ambulance sirens. As the vehicle approaches, the apparent pitch of the siren is increased, as the vehicle passes, the apparent pitch would decreased.

The correct answer is A ) the Doppler effect is the phenomenon being illustrated in the question.

If a sound with frequency fs is produced by a source traveling along a line with speed vs. If an observer is traveling with speed vo along the same line from the opposite direction toward the source, then the frequency of the sound heard by the observer is fo = c + vo c − vs fs where c is the speed of sound, about 332 m/s. (This is the Doppler effect.) Suppose that, at a particular moment, you are...

For this problem, assume that high frequency sound waves travel through human tissue at 1500 m/s (about the speed of sound in water). a) Measurements of the blood flow in the ascending aorta shows a maximum speed of 92.00 cm/sec. Assuming the ultrasound frequency used is 2.000000 MHz (the paper uses 2.25 MHz), calculate the frequency as seen by the blood that is traveling toward the ultrasound transducer at 92.00 cm/s. The transducer, which both transmits and receives the sound...

Two loudspeakers, 1.1 mm apart, emit sound waves with the same frequency along the positive xx-axis. Victor, standing on the axis to the right of the speakers, hears no sound. As the frequency is slowly tripled, Victor hears the sound go through the sequence loud-soft-loud-soft-loud before becoming quiet again. What was the original sound frequency? Assume room temperature of 20∘C∘C. Express your answer with the appropriate units. please write the answer neatly, another post similar to this one was difficult...
