Convert wavelength in metres to hertz
Wavelength in Metres
Wavelength in metres expresses the spatial period of a wave — the distance over which the wave shape repeats — measured in metres. For electromagnetic waves in vacuum, wavelength λ (m) = c/f, where c ≈ 2.998×10⁸ m/s. AM radio waves have wavelengths of hundreds of metres; visible light, around 400–700 nm.
Hertz
The hertz (Hz) is the SI unit of frequency, defined as one cycle per second. It is named after the German physicist Heinrich Hertz. Frequencies in everyday life range from a few hertz for sound waves to gigahertz for radio waves and processor clock speeds, and into terahertz for infrared light.
