Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the bright hydrogen emission lines. Key fact Line emission spectra are ...

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 ...

When studying the solar spectrum, researchers often search for specific emission lines: prominent wavelengths emitted by ions as their electrons transition from higher to lower energy levels.

Every now and again, the night sky lights up with a spectacular explosion that blazes with the most energetic light our Universe can produce. Known as gamma-ray bursts, they can release in a few ...

The right picture shows the visible spectrum of the sun lighting the blinds of the room. Specifics About CFL Emission Lines and Spectrometer Calibration The spectrometer must be calibrated every time ...

We present a synthetic rotation curve technique to analyze spatially resolved emission lines from faint galaxies. This algorithm takes into account important variables, such as intrinsic velocity ...
