They have a frequency of above 20,000Hz inaudible to human ear.
Sound waves- ultrasonic, sonic, or intrasonic are generally invisible. You cannot see sound.
whale can hear ultrasonic sound waves.
Bats produce ultrasonic sound waves to sense obstacles in their environment. These waves bounce back, allowing bats to navigate and locate objects in the dark.
Ultrasonic means 'faster than sound'. This means no sound wave can be faster than sound.
Ultrasonic sound.
No, ultrasonic wave do not travel at all in a vacuum.

No ultrasonic waves are not a form of electromagnetic wave. Ultrasonic waves are nothing more than high frequency sound waves. They can be made with a suitable speaker or transducer.
ultrasonic sound waves
Loudspeakers are designed to operate within the audible frequency range (20 Hz to 20 kHz) and are not capable of producing ultrasonic frequencies (above 20 kHz) due to limitations in their design and material properties. At higher frequencies, the components of the speaker system, such as the cone and coil, are not able to efficiently reproduce the ultrasonic waves, resulting in distortion or damage to the speaker. Specialized transducers or speakers designed for ultrasonic frequencies are needed to produce sound waves in the ultrasonic range effectively.
The wavelength of ultrasonic sound typically ranges from 1 mm to 1 cm, corresponding to frequencies higher than the upper limit of human hearing (20 kHz). Ultrasonic sound waves have shorter wavelengths compared to audible sound waves.
Volumetric properties, such as density or compressibility, can be determined using ultrasonic velocity measurements by analyzing the speed of sound waves as they travel through a substance. By applying the appropriate equations and principles of ultrasonic physics, researchers can correlate the velocity of sound with the material's volumetric properties. This method is commonly used in scientific research and industrial applications to characterize materials and understand their physical properties.
