Revise: Uses of X-rays and Gamma RaysX-rays are electromagnetic waves that can travel through some materials but are absorbed more strongly by others. This difference lets us observe an object's internal structure without cutting it open. An X-ray source sends radiation through the object towards a detector.
For an X-ray image, link the visible internal structure to different amounts of X-rays passing through different materials.
