Spectrum, in physics, the intensity of light as it varies with wavelength or frequency. An instrument designed for visual observation of spectra is called a spectroscope, and an instrument that photographs or maps spectra is called a spectrograph. Learn
Spectroscopy, study of the absorption and emission of light and other radiation by matter, as related to the dependence of these processes on the wavelength of the radiation. Spectroscopic analysis has been crucial in the development of the most fundamen

Our modern definition ofspectrumstarted out in the 1600s, when scientists used it to refer to the band of colors formed by a beam of light, like a rainbow. In physics, it’s a word that describes the distribution of something, like energy or atomic particles. We still use those scientifi...

The maximum spectral sensitivity is at 405 nm, while the resolving power of the spectrograph was λ/Δλ 250. Here, we report on the results for one particularly nice spectrum from a Leonid meteor at 03:24:40 UT. Numerous atomic emission lines of magnesium and iron were detected, with an...
This process is called emission. A spectrum is the wavelengths of light either absorbed or emitted by an atom or molecule. The spectrum, which corresponds to transitions between electronic energy levels, is unique. This allows us to identify atoms based on their spectrum. Atomic Absorption ...

These are known as electronic transitions, and the energy gap between the two levels generally corresponds to a photon in the UV or visible region of the electromagnetic spectrum.Absorption and emission of a photon by a material.These processes are demonstrated in the diagram above. The left-...
