This is shown below with the known colors from the atomic emission in the CFL annotating the spectrum. The spectroscope assembly discussed above can be quickly modified to include a sample holder as ...

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 ...

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 ...
