# How to calculate wavelength in nm

The power of short wavelength light sources in the EUV to X-ray range are often expressed as photon flux ( F) in the units of photons per second (ph/s). Average power is related to flux and photon energy by: P = F × E (equation 3) P = F × hc/ l (equation 4) P ( m W) = 1.989 × 10-10 × F / l (nm) (equation 5) For any given flux and wavelength ...

Imagine a very long wavelength of 75,000 km. Frequency = 300,000 km/s 75,000 km = 4 /s = 4 Hz. We can fit 4 of those wavelengths in 300,000 km, so it vibrates 4 times in 1 second. So the frequency is 4 Hz (4 per second) Or, the other way around, if we know it vibrates 4 times a second we can calculate its wavelength: Wavelength = 300,000 km/s 4 /s Peak Wavelength. We will use the SST-10-G as an example. The SPD below shows a typical set of normalized values measured using a spectrometer. There is a distinct peak value at 535 nm. This is the peak wavelength for this example SPD. The peak wavelength and associated SPD in W/nm are used for light calculations and lens/filter design.

How to calculate wavelength. In order to calculate the wavelength, we must divide the speed of the wave by its frequency. For this there is a specific formula that is: Wavelength = wave speed / frequency. Where: The wavelength is usually represented by the Greek letter lambda λ; The speed is usually represented by the letter υDominant Wavelength In order to calculate dominant wavelength, we must first introduce the identification of a color by its “x-y chromaticity coordinates” as plotted in the Chromaticity Diagram. The diagram enables us to quantitatively graph the hue and saturation of a particular color by its dominant wavelength and excitation purity ...
