What is ultrasonic waves write its properties and uses?

10 Important Properties of Ultrasonic Waves Property 1: Ultrasonic waves vibrate at a frequency greater than the audible range for humans (20 kilohertz). Property 2: They have smaller wavelengths. As a result, their penetrating power is high. Property 3: They cannot travel through vacuum.

Is ultrasonic waves harmful to humans?

Safety. Occupational exposure to ultrasound in excess of 120 dB may lead to hearing loss. Exposure in excess of 155 dB may produce heating effects that are harmful to the human body, and it has been calculated that exposures above 180 dB may lead to death.
