Waves with frequencies over 20,000 Hz are considered ultrasonic waves. They are higher in frequency than what humans can hear, and are commonly used in medical imaging, cleaning processes, and communication technologies.
for this answer it's false i made a 90 on this test :)
Sound waves with frequencies above 20,000 Hz are considered ultrasonic. These frequencies are above the upper limit of human hearing and are commonly used in applications like medical imaging, cleaning, and animal communication.
No, sound waves with frequencies higher than 20,000 Hz are referred to as ultrasonic waves, not subsonic waves. Subsonic waves are sound waves with frequencies lower than 20 Hz.
Ultrasound waves. These waves are used in medical imaging, cleaning processes and various other applications due to their high frequency and ability to penetrate surfaces.
False. Ultrasound waves are sound waves with frequencies above the range of human hearing, typically above 20,000 Hz, not less than 20 Hz.

People can typically hear sound waves with frequencies ranging from 20 Hz to 20,000 Hz. Frequencies below this range are infrasound (below 20 Hz), and frequencies above this range are ultrasound (above 20,000 Hz).
The frequencies (cycles per second) of the audible vibrations are between 20 Hz and 20000 Hz.
typically 20-20000 Hz - but this range will decrease with age
The beat frequency produced by two waves is calculated by finding the difference between their frequencies. In this case, the frequencies are 24 Hz and 20 Hz, so the beat frequency is 24 Hz - 20 Hz = 4 Hz. This means that the two component waves will produce 4 beats per second.
sound waves, between about 20 Hz to 20000 Hz (for most people).
False. Ultrasound waves are sound waves with frequencies above the range of human hearing, typically above 20,000 Hz, not less than 20 Hz.
typically 20-20000 Hz - but this range will decrease with age
Ultraviolet waves have frequencies ranging from about 7.5 × 10^14 Hz to 3 × 10^16 Hz.
