For other types of waves this may be constant or vary in complex ways across the spectrum.
Wavelength scans measure the absorbance and emission of light through a sample. Absorbance is proportional to concentration and a wavelength scan can be used to determine concentrations of a sample.
All particles which represents a quantum of light and other electromagnetic radiation is called photon. The photons with the highest energies are gamma or X-rays, UV light, Blue light, and radio waves.
It depends on the frequency; The equation for wavelength is 300/frequency in megahertz. A radio emitting energy at 30MHz is producing waves 10 meters long.But since radars usually work up in the SHF and EHF spectra, the wavelengths are measured in centimeters or millimeters. An example: You are a cop who catches speeders with a K-band radar. It, like every other K-band radar, emits at 24.150GHz, or 24,150MHz. So...using that equation, you will find the wavelength is 1.2 centimeters.
Different elements have different line spectra because each has a unique arrangement of energy levels for its electrons. When electrons transition between these energy levels, they emit or absorb specific wavelengths of light, creating distinct lines in the spectrum. This results in discrete lines rather than a continuous spectrum.
A more powerful version of Wi-Fi that can provide wireless internet access over wider geographic location such as a city.
The product of a wave's frequency and its wavelength is always its speed.
The product of a wave's frequency and its wavelength is always its speed.
It is a constant which is equal to the speed.

There are hundreds if not thousands of different categories for EM radiation that extend through history. From the broad: radio, microwave, infrared, visible, UV, X-ray, gamma, the modifiers "short wave" and "long wave"... to the specific colors of each line/ wavelength / frequency, to the characteristic spectra of the elements and / or chemical compounds.
550 nm sounds pretty much like a wavelength, so what's the question? It's in the visible spectra, the color green.
Barium has an atomic spectra of lines, not only one line (with one wavelength); I reccomend to consult a catalog of spectral lines. See the link below.
The extinction spectra is actually the measurement of light absorption in different mediums. This spectra is used in chemistry and biochemistry.
No, lines of a particular element do not appear at the same wavelength in both emission and absorption line spectra. In absorption spectra, dark lines are seen where specific wavelengths are absorbed by elements in a cooler outer layer of a star or a cooler interstellar cloud. In contrast, emission spectra display bright lines when elements emit specific wavelengths of light at higher energy levels.
Line spectra have zero width by definition. However, for measured data this is impossible because that would require infinite time to make the measurement. Electronic spectrum analyzers do the frequency measurements over a given period of time, and the minimal width of the spectral line is inversely proportional to the measurement time period. This is the case if the source of the energy is truly frequency (or wavelength) invariant. In physics, the measurement device may be optical, in which case the minimal width of the line spectra is dependent on the characteristics of that device. If the radiation from the sun is viewed using a prism, you will not be able to see any fixed spectral lines, since the energy source is heat radiation which is broad spectrum. Therefore, when the line spectra are very narrow, then the frequency/wavelength variation of the radiation source is very stable. The measurement device can also limit the width of the line spectra measurements. You would like to have it be able to show very thin widths so that the measurement device does not affect the accuracy of the measurement.
Different atoms have a different number of electrons. This is why they show different spectra.
