Introduction to the physics of light
... An absorption line is produced when a photon of just the right energy is absorbed by an atom, kicking an electron to a higher energy orbit. Other photons moving through the gas with the wrong energy will pass right on by the atoms in the thin gas. They make up the rest of the continuous spectrum you ...

... If more intense light falls on the photocathode, it will release more electrons but their energies, and their velocities, will remain the same. The energy of the photoelectrons depends on the frequency of the light: blue light produces more energetic photo-electrons than red light. The response o ...

Gamma spectroscopy
Gamma-ray spectroscopy is the quantitative study of the energy spectra of gamma-ray sources, in such as the nuclear industry, geochemical investigation, and astrophysics. Most radioactive sources produce gamma rays, which are of various energies and intensities. When these emissions are detected and analyzed with a spectroscopy system, a gamma-ray energy spectrum can be produced. A detailed analysis of this spectrum is typically used to determine the identity and quantity of gamma emitters present in a gamma source, and is a vital tool in radiometric assay. The gamma spectrum is characteristic of the gamma-emitting nuclides contained in the source, just as in optical spectroscopy, the optical spectrum is characteristic of the material contained in a sample.
