Doppler Effect Calculator vs Relativistic Doppler Effect Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Doppler Effect Calculator
Compute the observed frequency shift when a sound or wave source and observer move relative to each other. Perfect for physics coursework, radar, sonar, and astrophysics applications.
- Answers
- Observed Frequency (Hz)
- Inputs
- Source Frequency, Source Velocity, Observer Velocity, Wave Speed, Motion Direction
Relativistic Doppler Effect Calculator
Compute the observed frequency and wavelength when a light source moves toward or away from you at relativistic speeds. Used in astrophysics to analyze spectra of fast-moving stars, galaxies, and spacecraft.
- Answers
- Observed Frequency (Hz)
- Inputs
- Source Frequency, Relative Velocity, Motion Direction
