The instrument used to identify and draw sound waves is called a “sonar”. Sonar stands for Sound Navigation and Ranging. It emits sound waves into water and detects the echoes bounced back from objects, helping in navigation, communication, and underwater mapping.

The instrument used to identify and draw sound waves is called a “sonar” (Option [B]). Sonar, short for Sound Navigation and Ranging, is primarily used underwater to detect and locate objects by transmitting sound pulses and analyzing the echoes reflected back. This technology is essential for submarine navigation, underwater mapping, and fish detection in fishing. It works on the principle that sound waves travel through water and reflect off objects, allowing sonar systems to create detailed images or maps of underwater environments.
Radar (Option [A]), on the other hand, uses radio waves for detecting objects and is commonly employed in aviation, weather forecasting, and maritime navigation. “Pucker” (Option [C]) is not a recognized instrument for identifying or drawing sound waves. Therefore, out of the options provided, sonar specifically refers to the instrument used to detect and visualize sound waves underwater, distinguishing it from radar and unrelated terms like “Pucker”.
