🌊 Doppler Effect — Overview
The Doppler Effect is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. It is commonly heard when a vehicle sounding a siren approaches, passes, and recedes from an observer.
Blueshift: Frequency increases (wavelength decreases) when source and observer move closer.
Redshift: Frequency decreases (wavelength increases) when source and observer move apart.
📐 Core Formulas (Sound)
General Formula: $f_{obs} = f_s \left( \frac{v \pm v_o}{v \mp v_s} \right)$
Where:
$v$ = Speed of sound in medium
$v_o$ = Speed of observer
$v_s$ = Speed of source
$f_s$ = Source frequency
Sign Convention:
Top sign (+) for observer moving towards source.
Bottom sign (-) for observer moving away from source.
Top sign (-) for source moving towards observer.
Bottom sign (+) for source moving away from observer.
🚀 Relativistic Doppler (Light)
For light (electromagnetic waves), no medium is required. The formula depends on relative velocity $\beta = v/c$.
Approaching: $f_{obs} = f_s \sqrt{\frac{1 + \beta}{1 - \beta}}$
Receding: $f_{obs} = f_s \sqrt{\frac{1 - \beta}{1 + \beta}}$
⚠️ Important Notes
Speed of Sound: Varies by medium and temperature. In dry air at 20°C, $v \approx 343$ m/s.
Supersonic: If source speed exceeds wave speed ($v_s > v$), a shock wave (sonic boom) occurs. This calculator assumes subsonic speeds for sound.

Understanding the Doppler Effect
The Doppler effect occurs when the frequency of a wave changes due to the motion of either the source or the observer. This change is called the doppler shift frequency change.
For example:
When a sound source moves toward an observer, the frequency increases.
When it moves away, the frequency decreases.
This principle applies to different types of waves:
Sound waves
Light waves
Electromagnetic waves
Radio waves
A doppler effect physics calculator helps determine these frequency changes using established equations.

Where:
| Symbol | Meaning |
|---|---|
| f’ | Observed frequency |
| f | Source frequency |
| v | Speed of wave |
