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 else can I help you with?
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.
How is a wavelength measured?
A wavelength is a measure of the distance between two consecutive peaks (or troughs) of a wave. For electromagnetic radiation, the wavelengths range from 10^-11 to 10^3 metres - a factor of 100 trillion. There is, therefore, no single instrument which can be used to measure across such a range.
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 is the abbreviation for the units of measure of wavelengths of light?
The abbreviation for the units of measure of wavelengths of light is "nm" which stands for nanometers.
Can a nanometer measure a wavelength?
Yes, a nanometer can be used to measure wavelengths of light. For example, visible light has wavelengths ranging from about 400 to 700 nanometers. By using nanometers, scientists can accurately measure and describe the size of light waves.
What are the two way to measure wavelengths?
Wavelengths can be measured in meters (m) or nanometers (nm). Meters are commonly used for longer wavelengths, while nanometers are used for shorter wavelengths, particularly in the visible light spectrum.
What does the wavelengths measure?
It is the distance from peak to peak (or trough to trough) of a wave.
What is frequency of a measure of?
the number of waves per second (APEX)
The is the unit of measure for the frequency of wavelengths per second?
Hertz, condensed as "hz" when written.
How does one measure wavelengths?
Wavelengths can be measured by determining the distance between two corresponding points on a wave, such as from peak to peak or trough to trough. This distance is typically measured in meters, nanometers, or angstroms depending on the scale of the wavelength being measured. Instruments like spectrometers or diffraction gratings can also be used to measure wavelengths accurately.
The unit of measure for the frequency of wavelengths per second?
Frequency is measured in hertz (Hz) - cycles per second.
What instrument will measure the wavelengths of light absorbed by a solution?
A spectrophotometer is typically used to measure the wavelengths of light absorbed by a solution. This instrument can determine the amount of light of a specific wavelength that is absorbed by the solution, which can provide information about the composition of the solution.
What equipment is used wavelength?
Equipment used to measure wavelengths include spectrometers, such as UV-Vis spectrometers for ultraviolet and visible light, and infrared spectrometers for infrared light. For measuring specific wavelengths within a range, monochromators and filters can be used. Additionally, wavelength meters and spectrophotometers are commonly used to measure and analyze wavelengths in various applications.
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.
