X-rays are a form of electromagnetic radiation with distinct properties and applications across various fields. Here's a structured overview of their uses, basics, and significance:
- Categories: X-rays are part of the electromagnetic spectrum, categorized into different types based on wavelength: X-ray, gamma-ray, beta-ray, and alpha-ray.
- Wavelength Range: They span from very high-energy, short-wavelength (gamma-rays) to low-energy, long-wavelength (X-rays), with X-rays being the most common type.
Uses of X-rays
-
Medical Imaging:
- X-ray Tomography (CT Scans): Used to create detailed images of internal structures.
- X-ray Therapy: Applied in cancer treatment to shrink tumors.
-
Geology:
