What are characteristics of ultra sound

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.

Property 4: Ultrasonic waves travel at the speed of sound in the medium. They have maximum velocity in a denser medium.

Property 5: In a homogeneous medium, they travel at a constant velocity.

Property 6: In low viscosity liquids, ultrasonic waves produce vibrations.

Property 7: They undergo reflection, refraction and absorption.

Property 8: They have high energy content. They can be transmitted over a large distance without much loss of energy.

Property 9: They produce intense heat when they are passed through objects.

Property 10:Like sound waves, ultrasonic waves are longitudinal waves that produce alternate compressions and rarefactions.
