Wave Speed: The fundamental wave relationship. This free calculator solves for Wave speed, frequency, wavelength and shows every step.
Every wave obeys v = fλ: the speed equals how many wavelengths pass per second times their length. Speed is set by the medium — sound travels ~343 m/s in air but far faster in water and steel; light travels at 3 × 10⁸ m/s in vacuum and slows in glass.
A tone at f = 256 Hz with λ = 1.34 m in air. v = 256·1.34 ≈ 343 m/s (the speed of sound).
Acoustics and music, radio and antenna design, optics, ultrasound, telecommunications.
Wave Speed uses the formula v = f·λ. The fundamental wave relationship.
Choose which variable to solve for, enter the values you know (in any supported unit), and the calculator substitutes them into v = f·λ and shows every step of the working. It can solve for Wave speed, frequency, wavelength.
