The atoms decay back to lower levels by emitting light. Since the transitions are between distinct atomic energy levels, the emission lines in the spectra are narrow. The spectra of samples containing ...

In atomic emission spectroscopy, a sample is exposed to an electrical arc, a flame, or plasma to generate excited state atoms that are capable of emitting light. The unique emission spectrum of a ...

Researchers have exclusively observed molecules participating in hydrogen bonds in liquid water, measuring electronic and nuclear quantum effects that were previously accessible only via theoretical ...

Whilst microwave plasmas are nothing new around here, we were curious to see what happens at 20x the power, and since YouTuber [Styropyro] had put out a new video, we couldn’t resist seeing ...

For the first time, EPFL researchers have directly observed molecules engaging in hydrogen bonds within liquid water, ...

In view of the more recent work of Moseley on the high-frequency spectra of the ... Periodic Table (and has an atomic weight Which is four units less) while the emission of a beta particle leads ...

The plasma emission can, therefore, be resolved both spectrally and temporally to yield spectra containing the atomic emission lines corresponding to the atoms present in the plasma volume.

When a gas is very hot, it doesn’t emit all wavelengths of light. Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the ...

Infrared astronomy has revealed so much about the universe, ranging from protoplanetary disks and nebulae to brown dwarfs, ...

This causes line emission spectra to be produced, as shown below. This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of ...
