Wavenumber/Wavelength Converter. Starting with the highest frequencies, the spectrum is made up of gamma rays, x rays, ultraviolet, visible light, infra-red, microwave, and radio waves. For example: What is the wavelength of a 70 Hertz sound wave traveling at 343 meters per second? As the speed of light is constant, if you increase the frequency, the wavelength must decrease to maintain this equation and vice versa. The wave with the longest wavelength, radio waves, cannot be seen by the human eye, and therefore doesn't have a color. Check our De Broglie wavelength calculator to learn more about it. How do I calculate the wave length given only the frequency? Suppose there is a clocktower in your town that rings 12 times each day at noon. Enter the wavelength of the wave, i.e., 700nm700\ \text{nm}700nm. Photons are particles of light.
