Relate wave speed, frequency and wavelength for any wave type.
Wave speed is set by the medium, so frequency and wavelength are inversely related within it. A 440 Hz note in air has a wavelength of about 0.78 m. Because speed is fixed by the medium, raising frequency shortens wavelength proportionally — the basis of everything from antenna design to acoustics.
