WebbThe simplest picture is that light always travels at the speed of light. But in a material it travels at the speed of light until it hits an atom. It is then absorbed and re-emitted in the same direction, which takes a small amount of time. The more this happens, the slower the effective average speed. The denser the material, the more atoms ... WebbIn Radiography Testing the test-part is placed between the radiation source and film (or detector).
