Some Fundamental Definitions,collisions, and the associated cross section will be derived. Finally, we will examine the electric field of a moving charge, to explain at a fundamental level what radiation is. This will lead to find out the power emitted by an accelerating charge.

Beaming,hat these photons reach us though different paths, of different lengths. Then it is not true any longer that a moving sphere will be . or . as contracted in the direction of motion. We will derive that a sphere is seen rotated… and not contracted, since a rotated sphere does not change its shape. An

Then we will find out the typical frequencies after the scattering of a high energy particle and a seed photon. As for the synchrotron case, we w

Pairs,h enough, there is some chance that two photons interact and produce an electron–positron pair. This process can therefore be an important absorption process. On the other hand the produced pairs could again emit high energy photons making the entire process non-linear. This process sets a limit on
