Answer 2

Answer:  

The full form of SONAR is ‘Sound Navigation and Ranging’.

Explanation:

• This uses sound impulse given to sea water to find the depth of sea or ocean at a particular place. The procedure is quite simple.

• A sound wave is emitted from the surface of the ocean.

• It touches the ocean bed, gets reflected and returns to the surface of the ocean.

• The speed of ‘sound in sea water’ is known and the time is known hence the distance is the product of the time and the speed.
