Such sound is called ULTRASOUND. 20,000 Hz (20 kHz) is the approximate upper limit for the human ear.
Sounds with frequencies higher than 20000 Hz are considered ultrasonic and are typically outside the range of human hearing. These sounds can be produced by animals like bats and dolphins for echolocation, as well as certain electronic devices like ultrasonic sensors and medical equipment.
Bats can hear frequencies up to approximately 200,000 Hz, which is significantly higher than what humans can hear. They use echolocation to navigate and hunt for prey, emitting high-frequency sounds and listening for the echoes to locate objects in their environment.
for this answer it's false i made a 90 on this test :)
20,000 Hertz or simply 20 kHz, is taken to be the upper limit of hearing in younger, healthy humans. Sound frequencies higher than 20 kHz cannot be heard by humans, but can be heard by animals like dogs.
Sounds with higher pitch have higher frequencies, meaning the sound waves vibrate more rapidly. This results in the perception of a higher pitch. Sounds with lower frequencies have slower vibrations and are perceived as lower pitch.
No. The higher the frequency of a wave, the higher the energy.
Sounds with frequencies higher than 20000 Hz are considered ultrasonic and are typically outside the range of human hearing. These sounds can be produced by animals like bats and dolphins for echolocation, as well as certain electronic devices like ultrasonic sensors and medical equipment.
Yes, on the order of 1013 hertz higher.
yes dogs can detect lower or higher sounds than humans
I researched this question and apparently: "Dogs hear high tones in particular much better than humans do. Humans can pick up an average of 20,000 acoustic vibrations per second (kHz), whereas a dog is able to perceive between 40,000 and 100,000 vibrations." Although dogs can hear pretty well compared to humans, bats can detect twice as high a pitch as dogs.
Bats can hear frequencies up to approximately 200,000 Hz, which is significantly higher than what humans can hear. They use echolocation to navigate and hunt for prey, emitting high-frequency sounds and listening for the echoes to locate objects in their environment.
Ultraviolet rays have higher frequency (1 x 1016 to 8 x 1014 hertz) than the infrared rays(4 x 1014 to 1 x 1013 hertz).
No. Hz is the basic unit. MHz is "mega hertz," and mega means 1,000,000. GHz is "giga hertz" and giga means 1,000,000,000.

they can here higher sound than a human
Higher
Is 20000 greater than 25? If so, then it is a safe bet that 20000 km is longer than 25 km
