Question

what is sonar it working???​

Answer 1

$\large\underline{\blue{\sf \red{\maltese} Concept \: Of \: Sonar :-}}$

• ⭗ SONAR stands for Sound NAvigation Ranging.

• ⭗ 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.

Answer 2

$\huge\blue{\mid{\fbox{\tt{Answer❀✿°᭄}}\mid}}$

Sonar is a device that uses ultrasonic waves to measure the distance,direction and speed of underwater objects. Principle:It uses the phenomenon of echoes in determining the sea-depth and locating the presence of under-water objects.

Working of SONAR:

The transmitter in SONAR produces and transmits powerful ultrasonic waves. The ultrasonic waves travel through the water and after striking the target the beam is reflected from the seabed and is received by an under-water detector (mounted on the ship).

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. The sonar device measures how long it takes for the sound wave to travel down, hit an object and then bounce back up.
