Difference between thermal and electromagnetic radiation

Hi friend...
Thermal radiation is electromagnetic radiation. Electromagnetic radiation can be produced in many ways. As things get warmer, the electromagnetic radiation they emit becomes more intense and the peak of the radiation shifts to higher energies (greater frequencies or lower wavelengths).
There is a definite shape to the radiation from an ideal emitter and absorber, known as a "black body,"
Electromagnetic radiation can also be generated by accelerating electrons back and forth in wires. This is one way to generate radio waves. In fact electromagnetic radiation is produced anytime any electrically charged particle is accelerated. An apparent exception to this is electrons in atomic and molecular orbitals. This was a problem that led to the development of some of the ideas in quantum mechanics.
Electrons in an orbital can't emit radiation if there is no lower energy state for the electron to get to. However, if an electron in an atom or molecule is given enough energy to go to a higher energy state, it will emit radiation at a definite energy in dropping to a particular lower energy state. This is how line spectra are produced:
