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 ...

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.

In this comprehensive review of the radio astronomy of the Sun, thirteen researchers based in Australia summarise our present knowledge of solar radio emission at wavelengths of about one metre. CSIRO ...

Different stages of star formation can be measured in different ways, a number of which involve so-called emission lines – narrow regions within the electromagnetic spectrum where an object emits much ...

Practice with the RSpec software required. Turn off or dim as many lights as possible. Turn on the lamp. Observe how the camera software now picks up intensity peaks at various wavelengths. Click on ...

Their research highlights the reasons behind why the efficiency of single-photon emission ... emission wavelength moves from the visible range (violet to red) into the infrared spectrum of the ...
