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?
