Wave Speed Calculator – v = fλ

Calculate wave speed from frequency and wavelength using v = fλ.

Frequency (Hz)

Wavelength λ (m)

How It Works

Enter frequency in Hz and wavelength in meters. The calculator multiplies them to give wave propagation speed in m/s.

Formula

v = f × λ

Frequently Asked Questions

What determines wave speed?

Wave speed depends on the medium. Sound travels at ~340 m/s in air, ~1480 m/s in water, and ~5100 m/s in steel.

Does wave speed equal the speed of light for all EM waves?

Yes, all electromagnetic waves travel at approximately 3 × 10⁸ m/s in a vacuum, regardless of frequency.
