Effective Wavelength when Source Moves towards Observer Solution

STEP 0: Pre-Calculation Summary

Formula Used

Effective Wavelength = (Velocity of Sound-Velocity of Source)/Wave Frequency
λ_effective = (c-V_source)/f_W
This formula uses 4 Variables

Variables Used

Effective Wavelength - (Measured in Meter) - Effective Wavelength is the changed wavelength of light or sound due to the relative motion between the source and the observer in 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 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 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

λ_effective = (c-V_source)/f_W --> (343-80)/200
