Observed Frequency when Source Moves Away from Observer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Frequency Observed = Wave Frequency*(Velocity of Sound)/(Velocity of Sound+Velocity of Source)
F_o = f_W*(c)/(c+V_source)
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 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.

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 of Source: 80 Meter per Second --> 80 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

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

Evaluating ... ...

F_o = 162.174940898345

STEP 3: Convert Result to Output's Unit

162.174940898345 Hertz --> No Conversion Required

FINAL ANSWER

162.174940898345 ≈ 162.1749 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 Source Moves Away from Observer?

Observed Frequency when Source Moves Away from Observer calculator uses Frequency Observed = Wave Frequency*(Velocity of Sound)/(Velocity of Sound+Velocity of Source) to calculate the Frequency Observed, Observed Frequency when Source Moves Away from Observer formula is defined as a measure of the frequency of a wave that an observer detects when the source of the wave is moving away from the observer, which is affected by the speed of the source and the speed of light. Frequency Observed is denoted by F_o symbol.

How to calculate Observed Frequency when Source Moves Away from Observer using this online calculator? To use this online calculator for Observed Frequency when Source Moves Away from Observer, enter Wave Frequency (f_W), Velocity of Sound (c) & Velocity of Source (V_source) and hit the calculate button.

FAQ

What is Observed Frequency when Source Moves Away from Observer?

Observed Frequency when Source Moves Away from Observer formula is defined as a measure of the frequency of a wave that an observer detects when the source of the wave is moving away from the observer, which is affected by the speed of the source and the speed of light and is represented as F_o = f_W*(c)/(c+V_source) or Frequency Observed = Wave Frequency*(Velocity of Sound)/(Velocity of Sound+Velocity of Source). 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 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.

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

Observed Frequency when Source Moves Away from Observer formula is defined as a measure of the frequency of a wave that an observer detects when the source of the wave is moving away from the observer, which is affected by the speed of the source and the speed of light is calculated using Frequency Observed = Wave Frequency*(Velocity of Sound)/(Velocity of Sound+Velocity of Source). To calculate Observed Frequency when Source Moves Away from Observer, you need Wave Frequency (f_W), Velocity of Sound (c) & Velocity of Source (V_source). With our tool, you need to enter the respective value for Wave Frequency, Velocity of Sound & Velocity of Source 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 of Source. 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))
