Question

Who among the following are associated with SONAR?
A. Plumber
B. Doctor
C. Carpenter
D. Navigators

Answer 1

Hint: SONAR is having great use nowadays. SONAR stands for Sound Navigation and Radiation. From the name we can understand it has some association with navigation. It is helpful in exploring and mapping the ocean. It first came into use in the early twentieth century. This basic information can be used to answer this question.

Complete step-by-step answer:
SONAR is an abbreviation for Sound Navigation and Radiation. As the name itself implies that it is used for navigation. It uses ultrasound waves to find out the distance of an object from the transmitter or to get a clear picture of the path ahead when it is not possible to get the clear sight of the path. It helps to map and explore underwater. Submarines use this technology as it is not very easy to see underwater. It is also used in marine vessels. It has many advantages in the maritime world from mapping the seafloor to exploring shipwrecks.
Hence, navigators are associated with SONAR.
So, the correct answer is option D i.e. Navigators.

So, the correct answer is “Option D”.

Additional Information: SONAR works on the principle of echolocation. Echolocation is a physiological technique for locating distant as well as invisible objects. Echolocation technique is helpful in orientation, obstacle avoidance, food procurement and social interactions.

Note: Ultrasonic waves have higher frequency than normal sound waves. These waves are preferred as they do not get easily absorbed and perform reliable navigation and ranging. There are two technologies related to the term SONAR. The passive SONAR is primarily used for listening to sound made by vessels. The active SONAR is used in emitting pulses of sound and listening echoes.
