Answer:
Image- SONAR (Sound Navigation And Ranging)
parts: A- transmitter
B- ultrasound pulse
C- reflected ultrasound pulse
D- detector/ receptor
short note :Sonar stands for Sound Navigation And Ranging.
It is a device which is used to find of underwater objects. It is used to find distance, direction and speed. SONAR consists of a transmitter and a receptor or detector and is installed at the bottom of a ship.
The transmitter produces and transmits ultrasonic waves. These waves travel through sea water and after striking the objects on the bottom of sea, are reflected back and received and recorded by the detector.
The sonar device measures the time taken by ultrasound waves to travel from ship to bottom of sea and back to ship.
Half of this time gives the time taken by the ultrasound waves to travel from ship to sea bed.
Let the time interval between transmission and reception of ultrasound signal is t.
Speed of sound through sea water is v
Total distance travelled by waves = 2d.
Then, 2d = v × t.
This method of measuring distance is also known as ‘echo-ranging’.
Hope this helps :)
