An element can absorb photons of many different energies due to multiple possible transitions between different energy levels. In atomic spectra, absorption and emission lines are very sharp because ...

The emission spectrum of an element consisted of the photons (or radiation) electrons gave off when they jumped from higher orbits to lower ones. The photons carried away the angular momentum the ...

THIS atlas comprises the results of an investigation of the spark, arc, and flame spectra of most of the chemical elements. Twenty-eight charts are given showing heliographic reproductions of ...

The Kα emission line that corresponds to a dipole-allowed 2p–1s transition is commonly observed in X-ray emission spectra. XES is also used to perform a quantitative and qualitative analysis of ...

The TT-OES9000 Optical Emission Spectrometer by Torontech combines smart design with advanced technology to deliver precision without complication. Its layout supports both high-volume labs and ...

For Higher Physics, revise emission or absorption of certain frequencies of light from the elements and atomic line spectra.

Studying the line spectra produced by hot gases and absorbed by cooler gases allows us to identify the elements in stars. When a gas is very hot, it doesn’t emit all wavelengths of light. Hot ...

Each element has a unique emission spectrum. (Image credit: NASA) Modern spectroscopes often replace the prism with narrow slits called diffraction grating.

For a typical metallic sample containing manganese, iron, nickel, chromium, vanadium, etc., each element emits many wavelengths, resulting in a line-rich spectrum. For instance, iron emits just over ...

By analyzing the emission spectra of specific elements in the lab, then turning their spectroscopes on the stars, researchers could make out the chemical composition of everything from our sun to ...
