to detect ultrasonic waves ,place a sensitive flame in its path. if it flickers it proves its existence.
IT DETECT IT BY ULTRA VIOLET RAYS.
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.
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.
Cells that detect waves, specifically sound waves, are primarily found in the cochlea of the inner ear. These sensory cells, known as hair cells, convert mechanical vibrations from sound waves into electrical signals that the brain interprets as sound. Additionally, mechanoreceptors in the skin and other tissues can detect mechanical waves, such as pressure or touch.
A radio altimeter bounces radio waves off the ground to detect elevation.
Seismographs around the world detect P waves because these primary waves, or compressional waves, travel faster than S waves (secondary waves) and can move through both solid and liquid layers of the Earth. In contrast, S waves can only travel through solids, which is why some seismographs may not detect them if they are located in areas where the waves encounter liquid layers, such as the Earth's outer core. This difference in wave propagation explains why P waves are universally detected, while S waves are only recorded in specific locations.
infrared
Detect sound waves.
Sonar
They detect waves coming off of the closest stars
Different devices are used to detect different frequency ranges of electromagnetic waves. You simply can't use the same device to detect x-rays, than you would use to detect radio waves, for example.
