Observed Frequency when Source Moves towards Observer and Observer Moves Away Solution

STEP 0: Pre-Calculation Summary
Formula Used
Frequency Observed = ((Velocity of Sound-Velocity Observed)/(Velocity of Sound-Velocity of Source))*Wave Frequency
Fo = ((c-Vo)/(c-Vsource))*fw
This formula uses 5 Variables
Variables Used
Frequency Observed - (Measured in Hertz) - Frequency Observed is the number of oscillations made by the sound wave in one second. Its SI Unit is hertz.
Velocity of Sound - (Measured in Meter per Second) - Velocity of Sound is the distance covered by the sound in one second.
Velocity Observed - (Measured in Meter per Second) - Velocity Observed is the distance covered by the observer in one second.
Velocity of Source - (Measured in Meter per Second) - Velocity of Source is the distance covered by the source in one second.
Wave Frequency - (Measured in Hertz) - Wave Frequency is number of waves that pass a fixed point in given amount of time. Wave frequency can be measured by counting number of crests of waves that pass the fixed point in given time period.
STEP 1: Convert Input(s) to Base Unit
Velocity of Sound: 343 Meter per Second --> 343 Meter per Second No Conversion Required
Velocity Observed: 150 Meter per Second --> 150 Meter per Second No Conversion Required
Velocity of Source: 80 Meter per Second --> 80 Meter per Second No Conversion Required
Wave Frequency: 90 Hertz --> 90 Hertz No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Fo = ((c-Vo)/(c-Vsource))*fw --> ((343-150)/(343-80))*90
Evaluating ... ...
Fo = 66.0456273764259
STEP 3: Convert Result to Output's Unit
66.0456273764259 Hertz --> No Conversion Required
FINAL ANSWER
66.0456273764259 66.04563 Hertz <-- Frequency Observed

What is Doppler Effect?

The Doppler effect (or the Doppler shift) is the change in frequency of a wave in relation to an observer who is moving relative to the wave source. It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842.
