Sonar, short for Sound Navigation Ranging, is a technology that uses sound waves to detect objects underwater. It works by emitting sound pulses and analyzing the echoes that bounce back from objects, allowing for the measurement of distance and location. Sonar is commonly used in various applications such as navigation, fishing, and military operations.
Lewis Nixon did not invent sonar. Sonar was actually invented by Reginald Fessenden in 1913. Sonar stands for sound navigation and ranging, which is a technique that uses sound propagation to navigate, communicate with, or detect objects underwater.
No, using sonar will not kill you. Sonar is a technology that uses sound waves to detect objects underwater and is commonly used in various applications such as navigation and fishing. It is safe for humans to use sonar equipment.

The two main types of sonar are passive sonar and active sonar. Passive sonar listens for sounds in the water without emitting any signals, while active sonar sends out pulses of sound and listens for the echoes bouncing back.
Sonar can potentially harm or disorient a diver, but it is unlikely to directly kill them.
