Which of the following can be measured with the help of SONAR?

Correct option is D

The correct answer is (d) Distance, direction and speed of underwater objects.
· SONAR (Sound Navigation and Ranging) is a technology used to detect and measure the distance, direction, and speed of underwater objects.
· SONAR works by emitting sound waves and detecting the echoes that return after bouncing off objects.
· The time taken for the echoes to return allows for the calculation of the distance to the object, while the direction and speed can be determined based on the movement and angle of the returning sound waves.
· SONAR is widely used in submarines, ships, and marine exploration to detect underwater obstacles, marine animals, shipwrecks, and other objects in the ocean.
Additional Knowledge:
· Sound created by animals in the forest: This can be captured with acoustic devices, but SONAR is not used for this purpose.
· Distance of aircrafts: This is typically measured using RADAR (Radio Detection and Ranging), not SONAR.
· Sound pitch of aircrafts: Pitch is measured using audio devices or sound analyzers, not SONAR.
