The Doppler Shift Formula for the Frequency Detected Is Where

question 52

Multiple Choice

The Doppler shift formula for the frequency detected is where f ' is the frequency emitted, v is the speed of sound, v_D is the speed of the detector, and v_s is the speed of the source.Suppose the source is traveling at 5 m/s away from the detector, the detector is traveling at 7 m/s toward the source, and there is a 3 m/s wind blowing from the source toward the detector.The values that should be substituted into the Doppler shift equation are:

• A)v_D = 7 m/s and v_s = 5 m/s
• B)v_D = 10 m/s and v_s = 8 m/s
• C)v_D = 4 m/s and v_s = 2 m/s
• D)v_D = 10 m/s and v_s = 2 m/s
• E)v_D = 4 m/s and v_s = 8 m/s
