Underwater Communication
Underwater communication refers to the methods used to transmit information beneath the water's surface. Traditional radio waves do not travel well in water, so alternative techniques are employed, such as sound waves, light signals, and electromagnetic waves. Sonar is a common technology that uses sound to detect objects and communicate, especially in marine environments.
Another method of underwater communication is through the use of submarine cables, which can transmit data over long distances. Additionally, underwater drones and ROVs (remotely operated vehicles) often use acoustic modems to send and receive information while exploring or conducting research underwater.
