Question

The SONAR can detect the enemy ship using _________.

  1. Ultrasound
  2. Infrasound
  3. Audible sound
  4. None

hintHint:

Ultrasound

The correct answer is: Ultrasound


    • It is based on the principle of reflection of ultrasound waves.
    • SONAR (Sound navigation and ranging) is a method used in submarines and ships to detect far away objects, obstacles in water or enemy ship.
    • So, the correct option is a.
