the simplest way is to use a spectrometer more specifically emission spectrum in with a machine refracts the light radiation into colors which you can use to match up wavelength
another way is using planks law if you have the energy levels of the atom source for example/
E=hc/lambda where lambda is the wavelength, E is the energy, h is the planks constant and c is equal to the speed of light. we can rearrange this equation to give lambda=hc/E so for example a hydrogen emits radiation at E= to
3.01x10-19J we use the rearranged equation to give
(6.63x10-34)(3.00x10 8) / (3.01x10-19) = 6.63 x10-7 or 663nm

What is the correct way to measure wave length?
That will probably vary A LOT, depending on what type of wave you are talking about, and in what range the wavelength is. For example, the ratio between the frequencies - and therefore between the wavelengths - of different electromagnetic waves can be 15 orders of magnitude, or even more - and the techniques used to measure different ranges will certainly not be the same.
The candela is a unit of measurement of what?
A candela is a unit of measurement for light sources and light emissions. Light beams projects different color at different wavelengths, and a candela is used to measure the intensity of the light.
What has wavelengths between 380 and 750 nanometers?
Visible light
If a painted wall reflects light with wavelengths 600 to 700 nm but absorbs light with wavelengths 400 to 500 nm what color is it?
It will be a dark red solution- like liquid bromine
What causes the dark bands observed in a solar spectrum?
The dark bands are caused from the differnet chemical elements which absorb light at specific wavelengths.
How does one measure wavelengths?
There are multiple ways to measure wavelengths however one that I can think of is: An optical flat and a precision plano convex lens of known radius to form Newton's rings.
What does the wavelengths measure?
It is the distance from peak to peak (or trough to trough) of a wave.
What instrument will measure the wavelengths of light absorbed by a solution?
Google a Spectrophotometer
What is frequency of a measure of?
the number of waves per second (APEX)
Do you measure photons energy with wavelengths?
you see how close the wavelengths are-- the closer, the more powerful it is. Here are the wavelengths- from least powerful to most powerful: Radiowaves, Microwaves, Infared Waves, Visable Light, Ultraviolet, X-rays, and Gamma rays.
The is the unit of measure for the frequency of wavelengths per second?
Hertz, condensed as "hz" when written.
Can a nanometer measure a wavelength?
Yes. The wavelengths of visible light are usually measured in nanometers.
What do telescope measure?
Electromagnetic radiation in the wavelengths between a few hundred meters to a few millimeters.
What is a wavelengths?
The distance between consecutive crests of a wave. This serves as a unit of measure of electromagnetic radiation.
The unit of measure for the frequency of wavelengths per second?
Frequency is measured in hertz (Hz) - cycles per second.
What difference between pda and uv detector in hplc?
PDA - Photo diode array UV- Ultra violet with use of PDA detector, we can measure the area or height of particular peak at different wavelengths ranging from 200 to 800 nm by injecting the solution at once. Where as in uv detector we can measure the area or height of the peak only at two different wavelengths. But that wavelengths also to be selected before injecting the solution.
What does the SI unit measure meters by?
The current definition of the meter is a specified number of wavelengths of a specific color of LASER light.
