X-rays are dangerous because they have short wavelengths that can penetrate materials, and their high energy can damage matter.
The correct answer is: They have short wavelengths that can penetrate materials, and their high energy can damage matter.
X-rays are a form of electromagnetic radiation that have shorter wavelengths than visible light. Because of their short wavelengths, they have the ability to penetrate materials, such as the human body. This is why they are used in medical imaging to create images of bones and internal organs.
However, the high energy of X-rays can also damage matter. When X-rays interact with human tissue, they can ionize atoms and break chemical bonds, potentially causing damage to cells and DNA. This is why X-ray technicians wear protective gear, such as lead aprons, to minimize their exposure to X-rays and keep themselves safe.
