What is the full name of SONAR? A. Sound Neutralization and Ranging B. Sound Navigating and Reaching C. Sound Navigation and Ranging D. Sound Neuralization and Reaching Correct Answer C

The Correct Answer is Sound Navigation and Ranging.

  • The full name of SONAR is Sound Navigation and Ranging.

Key Points

  • Sonar is a technique that uses sound propagation usually underwater to navigate, communicate with, or detect objects on or under the surface of the water.
  • Two types of technology share the name "sonar": 
    • Passive sonar is essentially listening for the sound made by vessels; 
    • Active sonar is emitting pulses of sounds and listening for echoes.
  • Sonar may also be used for robot navigation and SODAR (an upward-looking in-air sonar) is used for atmospheric investigations

 

Additional Information

  •  A sonar device sends pulses of sound waves down through the water.
  • When these pulses hit objects like fish, vegetation, or the bottom, they are reflected back to the surface.  
  • This information enables the device to judge the depth of the object it reflected off.
  • The first recorded use of the technique was by Leonardo da Vinci in 1490 who used a tube inserted into the water to detect vessels by ear.

Read the passage carefully and choose the best answer to each question out of the four alternatives.
Eight north Indian Ocean countries, namely, Bangladesh, India, the Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand, were asked to contribute names so that a combined list could be compiled. Each country gave eight names and a combined list of 64 names was prepared. This list is currently in use, and all cyclones arising in the north Indian Ocean are named from this list, with one name from each country being used in turn. Almost 38 or 39 names from the list have been used up, but since many cyclones dissipate long before they hit land, their names rarely figure in the papers or other media. The names that people do know about, and remember are, naturally, those that were most destructive ones, or very recent. Aila, in 2009 is remembered with a shudder for the enormous destruction it caused in West Bengal and Bangladesh; Phaillin, also for the damage it caused when it hit the Odisha coast in 2013. Two harmless cyclones, which also might remain in peoples memory, are the more recent ones of 2014 — Hudhud, which threatened the east coast of India and Nilofar, which was expected to, but did not, devastate the western coast. The names in the cyclone list are usually words one associates with storms; words which mean water or wind or lightning in various national languages. Sometimes they are names of other things — birds or flowers or precious stones. The name Aila, contributed by the Maldives means fire, the name Phaillin from Thailand means sapphire, the name Hudhud from Oman is the name of a bird, probably the hoopoe, and the name Nilofar, given by Pakistan, is the Urdu name of the lotus or water lily. The eight names suggested by India, and which are in the list of 64, are Agni, Akaash, Bijli, Jal, Leher, Megh, Sagar and Vayu, meaning in that order, fire, sky, lightning, water, wave, cloud, sea and wind. Five of these names (that is, up to Leher) have been used so far.
For the next cyclone if it is the turn of an Indian name to be chosen, then what will be that name?
