"The Echo" is a natural phenomenon that occurs when sound waves bounce off surfaces and return to the listener. This effect can be experienced in various environments, such as mountains, canyons, or large empty spaces. The distance and type of surface affect how clearly the echo is heard. In addition to its natural occurrence, "The Echo" is also a term used in literature and music, often symbolizing repetition or reflection. It can be found in works by authors like Edgar Allan Poe and is a common theme in songs, where it represents emotions or memories that linger over time.
