Question

Why ultrasonic waves are suitable for sonar? What are the properties of ultrasonic waves?

Answer 1

Ultrasonic waves have ultrafrequency sound ( more than 20KHz)so they are suitable for sonar

Properties of Ultrasonic waves

- They have long penerating power

- They can be confined to large beam

Answer 2

Ultrasonic waves are high frequency waves that have a heating effect. They also have smaller wavelength than all the other waves and they form stationary wave pattern when passing through liquids. The ultrasonic waves have constant velocity in homogeneous medium.
