All waves of the EM. spectrum e.g. Radio waves Microwaves Light waves X-rays Gamma rays Cosmic Rays etc. Technically gravity waves and a couple other waves that relate to inter- and extra- atomic bonds

A microphone is an instrument that uses electricity to measure sound waves. It converts sound waves into electrical signals that can be amplified, recorded, or processed by electronic equipment.
A small microwave typically uses around 350 watts when in use.

No, light travels in waves too.
This sounds like a description of a sonar system, which uses sound waves to detect objects underwater by sending out a pulse of sound and measuring the time it takes for the sound waves to bounce back. Sonar systems are commonly used in navigation, fishing, and underwater mapping.
Sonar (Sound Navigation and Ranging) is a method that uses sound waves to find objects underwater. It works by emitting sound pulses and measuring the time it takes for the sound waves to bounce back, allowing for the detection of underwater objects such as submarines, ships, or marine life.
Ultrasound waves are high-frequency sound waves used for imaging internal organs, while lithotripsy shock waves are high-energy waves used to break down kidney stones or gallstones. Ultrasound waves are non-invasive and used for diagnostics, while lithotripsy shock waves are used to treat specific conditions by breaking down stones inside the body.
Electric Guitars,
An ultrasound test uses sound waves to create images of structures inside the body. It is a non-invasive imaging technique that is commonly used for diagnostic purposes.
Sonar is a technology that uses sound waves to detect objects underwater, while an echo is the reflection of sound waves off a surface back to the source. Sonar is used for navigation, communication, and detecting underwater objects, while an echo is a natural phenomenon that occurs when sound waves bounce off surfaces.
