Physics
Wave Speed
Calculate wave speed from frequency and wavelength.
v = fλ
Formula Explanation
Wave speed equals frequency multiplied by wavelength.
Variables Explained
v = Wave speed; f = Frequency in Hz; λ = Wavelength in metres.
Solved Example
A wave has frequency 20 Hz and wavelength 3 m.
v = 20 × 3 = 60 m/s.
