Open in App
Solution
The correct option is D ultrasonic waves
Answer is D.
SONAR is the best example that illustrates how a ship on the ocean utilizes the reflecting properties of sound waves to determine the depth of the ocean. A sound wave is transmitted and bounces off the seabed. Because the speed of sound is known and the time lapse between sending and receiving the sound can be measured, the distance from the ship to the bottom of the ocean can be determined. This technique is called sonar (SOund Navigation And Ranging).
A common use of ultrasound is in SONAR. Ultrasonic waves are used in SONAR instead of audible sound waves.
