X-rays penetrate objects that are impenetrable for visible light. The absorption depends on the thickness and type of the material. This dependence is demonstrated in a qualitative manner on a fluorescent screen with the aid of various different absorption specimens.
Tasks
- Observe the transmission of X-rays as a function of the material thickness.
- Determine how the atomic number of the elements in a material affects the transmission of X-rays.
Learning objectives
- X-ray tube
