You hear something slitering toward you in the dark. You know from past experience that somethings slither with a frewuency of 130 Hz. If you hear a frequency of 130+17 Hz, how fast is the litherer slithering toward you (in m/s)? The speed of sound is 300 m/s
Is is a doppler effect problem? But there is no wavelength given in here? Can anybody tell me how to do it?
The Doppler effect is a phenomenon that occurs when there is a relative motion between a source of sound or light and an observer. This results in a change in the perceived frequency of the sound or light waves.
If the problem involves the motion of a source of sound or light, or the motion of an observer relative to a source of sound or light, then it is likely a Doppler effect problem. Look for keywords such as "moving," "approaching," or "receding."
The formula for calculating the Doppler effect is: f' = (v ± vo) / (v ± vs) * fWhere f' is the perceived frequency, v is the speed of sound or light, vo is the velocity of the observer, vs is the velocity of the source, and f is the actual frequency of the source.
No, the Doppler effect can also be observed with other waves, such as water waves or seismic waves. It is a general phenomenon that occurs with any type of wave.
The Doppler effect is used in a variety of real-life applications, such as in weather radar to track the movement of storms, in medical imaging to create images of moving organs, and in astronomy to measure the speed and distance of celestial objects. It is also used in traffic speed cameras and police radars to measure the speed of moving vehicles.
