SONAR refers to Sound Navigation and Ranging. The principle of reflection of sound is used in SONAR. SONAR is used to measure the depth of the ocean. Ultrasonic waves are sent from the ship down into the sea. They are received back after reflection from the sea bed. The depth is calculated by noting the time period.
