Every wave — sound, light, or water ripples — has a speed, a frequency (how many wave cycles pass a point each second), and a wavelength (the distance between successive peaks).
Every wave — sound, light, or water ripples — has a speed, a frequency (how many wave cycles pass a point each second), and a wavelength (the distance between successive peaks). These three are always linked by one simple equation. This calculator finds any one of them from the other two.
A sound wave travels at 340 m/s with a frequency of 170 Hz. Leaving Wavelength blank: Wavelength = 340 / 170 = 2 m.
Wave speed = frequency × wavelength (v = fλ), so for waves traveling at a constant speed (like light), frequency and wavelength are inversely proportional.
Since the speed of light is constant, increasing frequency must decrease wavelength proportionally to keep their product constant.
Typically the speed of light in a vacuum, approximately 299,792,458 m/s, unless the calculator specifies a different medium.
