"can't be heard by humans."
for this answer it's false i made a 90 on this test :)
False. Ultrasound waves are sound waves with frequencies above the range of human hearing, typically above 20,000 Hz, not less than 20 Hz.
Sound waves with frequencies above 20 kHz are referred to as ultrasonic waves. These frequencies are beyond the range of human hearing, but they are used in applications such as medical imaging, cleaning, and communication systems.
No, the speed of ultrasonic sound waves is higher than that of audible sound waves. Ultrasonic waves have frequencies above the range of human hearing (above 20 kHz), while audible waves have frequencies within the range of human hearing (20 Hz to 20 kHz).
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.
Sound waves with frequencies above the normal human range of hearing are called ultrasoundUltrasoundUltrasonic for frequencies higher than a human can hear, and infrasonic for those frequencies below the human threshold of hearing.

Ultrasonic and Infrasonic sound waves are waves that are not audible to human beings. The audible region contains sound waves of 16 Hz to 20,000 Hz.Infrasonic sound waves have frequencies below 16 Hz. For example, an earthquake.Ultrasonic sound waves have frequencies above 20,000 Hz. For example, x-rays.Grade 11 Physics
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).
No, the speed of ultrasonic sound waves is higher than that of audible sound waves. Ultrasonic waves have frequencies above the range of human hearing (above 20 kHz), while audible waves have frequencies within the range of human hearing (20 Hz to 20 kHz).
sound waves with frequencies 20 hertz or lower are infrasonic and waves above 20,000hertz are ultra sonic!
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.
Sound waves have wavelengths and frequencies.
No. The frequencies determine the sound.
