Observed Frequency when Observer Moves towards Source and Source 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
F_o = ((c+V_o)/(c+V_source))*f_W
This formula uses 5 Variables

Variables Used

Frequency Observed - (Measured in Hertz) - Frequency Observed is the number of oscillations or cycles of a wave that an observer detects per second due to the Doppler Effect.
Velocity of Sound - (Measured in Meter per Second) - Velocity of Sound is the speed at which sound waves propagate through a medium, affected by the Doppler Effect, resulting in wavelength changes.
Velocity Observed - (Measured in Meter per Second) - Velocity Observed is the velocity at which the wave is received by the observer, affected by the motion of the source and observer.
Velocity of Source - (Measured in Meter per Second) - Velocity of Source is the speed at which the source of a wave is moving relative to an observer, affecting the wavelength of the emitted wave.
Wave Frequency - (Measured in Hertz) - Wave Frequency is the number of oscillations or cycles of a wave per second, affected by the relative motion of the source and observer.

STEP 1: Convert Input(s) to Base Unit

Velocity of Sound: 343 Meter per Second --> 343 Meter per Second No Conversion Required
Velocity Observed: 283 Meter per Second --> 283 Meter per Second No Conversion Required
Velocity of Source: 80 Meter per Second --> 80 Meter per Second No Conversion Required
Wave Frequency: 200 Hertz --> 200 Hertz No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F_o = ((c+V_o)/(c+V_source))*f_W --> ((343+283)/(343+80))*200

Evaluating ... ...

F_o = 295.981087470449

STEP 3: Convert Result to Output's Unit

295.981087470449 Hertz --> No Conversion Required

FINAL ANSWER

295.981087470449 ≈ 295.9811 Hertz <-- Frequency Observed
