Observed Frequency when Observer Moves Away from Source Solution

STEP 0: Pre-Calculation Summary

Formula Used

Frequency Observed = Wave Frequency*((Velocity of Sound-Velocity Observed)/Velocity of Sound)
F_o = f_W*((c-V_o)/c)
This formula uses 4 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.
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.
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.

STEP 1: Convert Input(s) to Base Unit

Wave Frequency: 200 Hertz --> 200 Hertz No Conversion Required
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

STEP 2: Evaluate Formula

Substituting Input Values in Formula

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

Evaluating ... ...

F_o = 34.9854227405248

STEP 3: Convert Result to Output's Unit

34.9854227405248 Hertz --> No Conversion Required

FINAL ANSWER

34.9854227405248 ≈ 34.98542 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.

How to Calculate Observed Frequency when Observer Moves Away from Source?

Observed Frequency when Observer Moves Away from Source calculator uses Frequency Observed = Wave Frequency*((Velocity of Sound-Velocity Observed)/Velocity of Sound) to calculate the Frequency Observed, Observed Frequency when Observer Moves Away from Source formula is defined as the frequency of a wave measured by an observer moving away from the source, which changes due to the relative motion between the observer and the source, resulting in a shift in the frequency perceived by the observer. Frequency Observed is denoted by F_o symbol.

How to calculate Observed Frequency when Observer Moves Away from Source using this online calculator? To use this online calculator for Observed Frequency when Observer Moves Away from Source, enter Wave Frequency (f_W), Velocity of Sound (c) & Velocity Observed (V_o) and hit the calculate button. Here is how the Observed Frequency when Observer Moves Away from Source calculation can be explained with given input values -> 185.0729 = 200*((343-283)/343).

FAQ

What is Observed Frequency when Observer Moves Away from Source?

Observed Frequency when Observer Moves Away from Source formula is defined as the frequency of a wave measured by an observer moving away from the source, which changes due to the relative motion between the observer and the source, resulting in a shift in the frequency perceived by the observer and is represented as F_o = f_W*((c-V_o)/c) or Frequency Observed = Wave Frequency*((Velocity of Sound-Velocity Observed)/Velocity of Sound). Wave Frequency is the number of oscillations or cycles of a wave per second, affected by the relative motion of the source and observer, 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 is the velocity at which the wave is received by the observer, affected by the motion of the source and observer.

How to calculate Observed Frequency when Observer Moves Away from Source?

Observed Frequency when Observer Moves Away from Source formula is defined as the frequency of a wave measured by an observer moving away from the source, which changes due to the relative motion between the observer and the source, resulting in a shift in the frequency perceived by the observer is calculated using Frequency Observed = Wave Frequency*((Velocity of Sound-Velocity Observed)/Velocity of Sound). To calculate Observed Frequency when Observer Moves Away from Source, you need Wave Frequency (f_W), Velocity of Sound (c) & Velocity Observed (V_o). With our tool, you need to enter the respective value for Wave Frequency, Velocity of Sound & Velocity Observed and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Frequency Observed?

In this formula, Frequency Observed uses Wave Frequency, Velocity of Sound & Velocity Observed. We can use 3 other way(s) to calculate the same, which is/are as follows -

Frequency Observed = ((Wave Frequency*(Velocity of Sound-Velocity Observed))/(Velocity of Sound+Velocity of Source))
Frequency Observed = ((Wave Frequency*(Velocity of Sound+Velocity Observed))/(Velocity of Sound-Velocity of Source))
Frequency Observed = (Velocity of Sound-Velocity Observed)/Wavelength
