In the 19th century, a sailor by the name of Samuel F.B. Morse developed what would become known as the "Morse Code." Morse Code is a way of communicating through patterns of dots or dashes that represent letters or numbers. When one person taps out morse code with two fingers, it sounds like various beeping noises, but when it is transmitted over radio waves across long distances, it becomes an understandable language for those listening in on their radios.
Morse code has proven to be an important form of communication for both professional and amateur radio operators. It consists of a series of dots and dashes, each dash representing a longer pulse than the dot. The Morse code was originally developed in 1838 by Samuel Morse for Morse's electric telegraph but was not widely adopted until the International Morse Code Congress in 1865.
