Unformatted text preview: Look at radiation from an accelerated charge a P Charge at q E field felt at point P (distance R from q) from the acceleration is BE Warren, pg 1 v q R Charge at q Has acceleration a R c qa 2 sin q = charge See David Griffiths, introduction to electrodynamics, 2 nd ed., pg a = acceleration c = sp light 401 405 = angle between the scattering direction and the direction of acceleration of the electron E field : is in the plane of R and a electron. Has magnitude that depends upon asin Consider single free electron at origin We want to find intensity of scattered radiation at point P Unpolarized incident beam along x axis BE Warren, pg 1 y Top view P Y is to the R vector, so not quite Y Point P is distance R from the electron and Angle from axi Top view x E OY Y See griffiths for proofs use o match Cullity Point P is distance R from the electron, and Angle from x axis Choose the other axes (y,z) so that P is in the XY plane...
