Want this question answered?
The wavelength IS 518 nanometers.... but in meters, it is expressed as 5.18 x 10-7 m. when you multiply by the conversion factor of 10-9
The give-away should be the word "length" which is hidden in the word "wavelength". Wavelength has the dimensions of length, and is most often stated in meters or centimeters (radio), nanometers (light), etc.
Red is in the range of 635-700 nanometers (nm).
Speed (of a wave) = frequency x wavelengthTherefore, you have to: * Convert the wavelength to meters. * Divide the speed of light - which is 300 million meters/second - by this wavelength. The answer will be in Hz.
Wavelength x frequency = speed (of the wave), therefore, the frequency is the speed divided by the wavelength. If you are talking about an electromagnetic wave in a vacuum, its speed is approximately 300,000,000 m/s. Also, don't forget to convert the nanometers to meters before doing the division.

Answer - meters or derivations of meters e.g micrometers, nanometers etc
Usually, no. The wavelength of visible light is usually measured in nanometers. Only larger forms of electromagnetic radiation, like radio waves, are measured in meters.
Just divide the speed of light (in meters/second) by the frequency (in hertz) - that will give you the wavelength (in meters). You can then convert that to nm.

speed of light in meters per second / wavelength in meters = frequency in Hz299 792 458m/s / 0.000000690m = 434481823188406Hz = 434481823188.4KHz =434481823.2MHz = 434481.8GHZ = 434.5THz
Almost exactly 102
0.3 meters=300,000,000 nanometers
2 meters = 2,000,000,000 nanometers
To convert from nanometers to meters, divide by 1,000,000,000.
To convert meters to nanometers, multiply by a billion.
Wavelength is the distance between repeating units of a propagating wave of a given frequency. For light waves, this value is often given in nanometers, abbreviated as "nm". A nanometer is 0.000000001 meters.
