Wave Speed Calculator
Calculate wave speed from frequency and wavelength.
Wave Speed Formula
v = f × λ.
Understanding Wave Speed
Wave speed is the rate at which a wave disturbance travels through a medium or through space. It equals frequency multiplied by wavelength, linking how often cycles occur with the distance between repeating points on the wave.
Example Calculation
A wave with frequency 50 Hz and wavelength 2 m travels at 50 × 2 = 100 m/s.
Factors and Interpretation
For many waves, the medium determines wave speed. If speed stays constant, increasing frequency shortens wavelength. Sound speed depends on the medium and temperature, while electromagnetic waves in vacuum travel at the speed of light.
Frequently Asked Questions
Is wave speed the same as particle speed?
No. The medium’s particles may oscillate locally while the wave pattern travels through the medium.
What if frequency doubles?
If wave speed stays constant, wavelength is halved.
Can wave speed change?
Yes. Entering a different medium can change propagation speed and wavelength.

Formula and Practical Limits
Wave speed satisfies v = fλ for a periodic wave. Frequency is set by the source while wavelength changes when wave speed changes between media; use compatible units throughout.
