Select the appropriate Doppler equation when source is approaching the stationary observer where fo is the observed frequency, fs is frequency of source, v is the speed of sound, vs is the speed of source relative to observer?
Options:
Answer:
Select the appropriate Doppler equation when source is approaching the stationary observer where fo is the observed frequency, fs is frequency of source, v is the speed of sound, vs is the speed of source relative to observer fo = v/v+vs fs.
