The velocity of sound is 340 m/s with respect to the medium (air). The point of the exercise is that the speed of the source (the jet) is irrelevant.Gear2d said:The answer for this is 340m/s. I was wondering why.
That's a pretty wild statement. You're right, the speed of sound most definitely depends on the medium. (What book is that, by the way?) What was the context of that statement?Because all the book states is that wave velocity is INDEPENDENT of medium (I thought velocity of a wave was medium dependent).
The Doppler effect is the change in frequency or wavelength of a wave relative to an observer who is moving relative to the source of the wave. This effect is commonly observed with sound waves, where a moving source will cause a change in the perceived pitch of the sound.
The Doppler effect does not directly affect the velocity of a wave. It only changes the frequency or wavelength of the wave as perceived by an observer. The actual velocity of the wave remains constant.
The main factors that influence the Doppler effect are the relative velocities of the wave source and the observer, as well as the speed of the wave itself. Additionally, the medium through which the wave is traveling can also affect the perceived frequency or wavelength.
The Doppler effect has various practical applications, such as in radar and sonar systems, where it is used to measure the velocity of moving objects. It is also used in medical imaging techniques, such as ultrasound, to detect and monitor blood flow. In astronomy, the Doppler effect is used to determine the velocity of celestial objects.
Yes, the Doppler effect can be observed with any type of wave, including sound waves, light waves, and water waves. However, the perceived change in frequency or wavelength may vary depending on the type of wave and the relative velocities of the source and observer.
