👉 Propagation in mathematics refers to the process by which information or data is transferred between two different points through a medium, such as light, sound, or electromagnetic waves. This transfer occurs at the speed of light, making it possible for information to travel across vast distances without being lost or damaged. In the context of computer science and signal processing, propagation refers to the movement of signals from one point to another, usually by means of a medium (such as air, water, or any other physical medium)
