IT DETECT IT BY ULTRA VIOLET RAYS.
to detect ultrasonic waves ,place a sensitive flame in its path. if it flickers it proves its existence.

To make sound, three things are needed: a source of vibration, a medium through which the sound waves can travel, and a receiver to detect and interpret the sound waves.
Sonar technology uses sound waves to detect objects underwater. When the sound waves hit an object, they bounce back to the device, allowing it to calculate distance, shape, and size of the object. By measuring the time it takes for the sound waves to return, sonar can create a detailed image of the underwater environment.
Humans cannot detect electromagnetic waves outside of the visible light spectrum, such as ultraviolet light, infrared radiation, and radio waves. Additionally, humans cannot directly detect gamma rays and X-rays.
Yes, seismograph stations around the world can detect both P-waves and S-waves. P-waves are the fastest seismic waves and are typically detected first, followed by the slower S-waves. The ability of seismographs to detect these waves allows scientists to study and monitor earthquakes globally.
anything warm rleases infra red waves the hotter an object is the more it releases. an inrer red camra detect infra and makes an image out of it.
You can detect invisible electromagnetic waves using specialized equipment such as antennas or receivers that are designed to pick up specific frequencies of electromagnetic radiation. These devices can convert the waves into a form that is visible or audible to humans, allowing us to detect and measure the presence of electromagnetic waves.
The process of recording sound waves to create an image of organs is known as ultrasound imaging. During an ultrasound scan, high-frequency sound waves are emitted from a transducer and bounce off internal structures in the body. The returning sound waves are then translated into an image that can be used to visualize organs and tissues in real-time.
To make the aircraft very difficult to detect on radar. It has about the same image on radar as a hummingbird.
A radio altimeter bounces radio waves off the ground to detect elevation.
