Wave Speed, Frequency and Wavelength Calculator
Enter a wave's frequency and wavelength to calculate its speed of propagation.
Wave Speed, Frequency and Wavelength Calculator
Calculates wave speed from a wave's frequency and wavelength using the fundamental wave equation.
This calculator applies the fundamental wave equation, v = f × λ (speed equals frequency times wavelength), which holds for any type of wave including sound, light, and water waves. Given any two of frequency, wavelength or speed you can solve for the third, but this version is set up to compute speed directly from frequency and wavelength — handy for physics coursework, acoustics, or basic optics and radio-wave calculations.
Example
- With the default values shown above, this calculator returns: Wave Speed ≈ 343.2 m/s.
Frequently Asked Questions
What is the wave equation?
Wave speed equals frequency multiplied by wavelength (v = f × λ) — it applies to all wave types, including sound, light and water waves.
What do the default values represent?
440 Hz and roughly 0.78 m wavelength correspond approximately to the musical note A4 traveling as sound through air, giving a wave speed close to the familiar ~343 m/s speed of sound.
