The anode is tilted by a particular angle to direct the rising X-rays in the appropriate direction. Usually Every electron is slowed down or deflected many periods so it results in the creation of a number of photons.
When a monochromatic X-ray beam traverses a homogeneous item with absorption coefficient μ, Based on Lambert-Beer’s legislation, the observed intensity I is related to the intersection size of the article x and the ray:
The attenuation coefficient μ is usually Power dependent. When polychromatic X-rays are taken under consideration, we get
