Calculate the observed wavelength due to the Doppler Effect. Our intuitive calculator helps you determine the shifted wavelength by considering the speed of the wave, source, and observer, along with their respective directions and the original wavelength. It's an essential tool for understanding wave phenomena in various physics applications, from sound to light.

Formula for Doppler Effect Wavelength
The formula used to calculate the observed wavelength (λobs) due to the Doppler Effect is:
λobs = λ0 × ( (v ± vs) / (v ± vo) )
Where:
λobs: Observed Wavelength (in meters, m)λ0: Original (Source) Wavelength (in meters, m)v: Speed of Wave in the medium (e.g., speed of sound in air, speed of light in vacuum) (in meters per second, m/s)- Numerator term (
v ± vs):- Use
v - vsif the source is moving towards the observer. - Use
v + vsif the source is moving away from the observer.
- Use
- Denominator term (
v ± vo):- Use
v + voif the observer is moving towards the source. - Use
v - voif the observer is moving away from the source.
- Use
This formula accurately accounts for the relative motion between the source and observer, explaining the shift in wavelength experienced.
