Document Summary
It does not matter what blackbody is made from i. e iron,nickel,glass. Graphs will all be the same and only depend on temperature. Electrons can only be in specific orbits with specific energies. Spectra provide a powerful means for astronomers to study objects in the universe, because they trace the behavior of matter at the microscopic level. Atoms can emit light (pieces of light are photons" as an electrons drops from high energy to low energy orbit. The energy difference is used to create a photon. When we look at a collection of millions of atoms, with electrons dropping and emitting millions of photons. Atoms can absorb photons) upward transition of electrons produce absorption lines) An electron absorb a photon and converts the photon energy and so he electron can jump to a higher energy orbit. Stars (all wavelength is generated inside continuous spectra)
