Doppler Effect Calculator vs Relativistic Doppler Shift 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 Shift Calculator
Computes the observed frequency of light or radio waves when the source and observer move relative to each other at relativistic speeds. Essential for astronomy, radar physics, and understanding redshift in cosmology.
- Answers
- Observed Frequency (Hz)
- Inputs
- Source Frequency, Relative Velocity, Motion Direction
