In the context of Physics and Medicine, X-rays are electromagnetic waves used for various purposes depending on how they interact with matter. Here is a brief breakdown of each option from your test:
A. Diagnosis (Correct Answer)
Diagnosis refers to the process of identifying a disease, condition, or injury. Because X-rays can pass through soft tissue but are absorbed by dense objects like bone or metal, they are the primary tool used to "see" inside the body to detect foreign objects (like a swallowed pin) or broken bones.
B. Therapy
Therapy (specifically Radiotherapy) involves using high-energy X-rays or other radiation to treat a condition rather than just identify it. It is most commonly used in oncology to destroy cancer cells or shrink tumors by damaging their DNA.
C. Crystallography
Crystallography is a branch of science used to determine the atomic and molecular structure of a crystal. By aiming X-rays at a crystal, the rays diffract (bend) into a specific pattern. Scientists analyze this pattern to map out how atoms are arranged in substances like DNA, minerals, or metals.
D. Mammography
Mammography is a specific type of medical imaging that uses low-dose X-rays to examine the human bosom. It is a specialized form of diagnostic X-ray used specifically for the early detection and screening of bosom cancer.

Crystallography is legit here because.
X-ray crystallography is used to check the internal structure of a body.
Majorly X-ray is used to check internal structure of something
