Wavelength in nanometers to Cycle per second Converter
Use this page to convert wavelength in nanometers values into cycle per second, with background details, formulas, a worked example, and a quick conversion table.
Conversion formula
This conversion uses an offset formula rather than a single multiplier because the temperature scales start from different zero points.
nm wavelength to cycle/s: Apply the scale formula and then add or remove the required offset.
Example: 1000000000 nm wavelength = 299,792,458 cycle/s
Wavelength in nanometers
Frequency in hertz equals the speed of light divided by wavelength in meters, after converting nanometers to meters.
History: Nanometer wavelengths are standard for visible and ultraviolet light.
Current use: Used for visible light, LEDs, lasers, spectroscopy, and optical filters.
Also written as nm wavelength, nanometer wavelength, nanometre wavelength, wavelength nanometers.
Cycle per second
One cycle per second is equal to one hertz.
History: Cycles per second was common before hertz became the formal SI name.
Current use: Used mainly for legacy frequency references.
Also written as cycle/s, cycles per second, cps.
