physics of imaging

Imaging in physics involves capturing visual representations of objects or phenomena using various methods. It relies on principles of light and electromagnetic waves. For example, in photography, light reflects off objects and enters a camera, where it forms an image on a sensor or film. In medical imaging like X-rays, high-energy radiation reveals internal structures. Techniques like MRI use magnetic fields and radio waves to generate images of the body's tissues. Overall, imaging combines optics, waves, and technology to visualize and understand the world around us, providing crucial insights in fields ranging from medicine to astronomy.
