Wave Speed Equation: v = fλ

The fundamental relationship connecting wave speed, frequency, and wavelength:

v = f × λ

Where:

• v = wave speed (m/s)

• f = frequency (Hz)

• λ = wavelength (m)

Example: If wavelength is 2 m and frequency is 3 Hz, then wave speed = 3 × 2 = 6 m/s

Math takeaway: Higher frequency OR longer wavelength means faster waves.
