Question

Are ultrasonic waves capable of traveling very large distances in a specific direction?If yes,then what's the reason behind it?

Answer 1

The ultrasonic waves are the waves which have a frequency greater than 20 KHz. Because of this high frequency, they are more energetic, and they travel large distance with minimum loss of energy. The intensity and speed of these waves depends on the frequency. Higher the frequency, higher will be the speed, and large distance gets covered with it.
