The X-ray experiment in the 1st year laboratory involves a high voltage (up to 28 kV) source of electrons which hit a target made of copper. This causes the electrons to decelerate, which results in the emission of "Bremstrahlung" X-rays, as well as characteristic peaks. The maximum X-ray energy is 28 keV. The door of the X-ray set is made of leaded glass. This attenuates the X-rays, according to the following equation: lo exp (-ut) Here l is the transmitted...
