SONAR employs reflection of sound.
Hence, the given statement is false.
SONAR is a technique that uses the reflection of sound to find the distance between objects.
Which of the following device works on the principle of multiple reflection of sound?
a) bulb horn b) RADAR c) SONAR d) gaiter
A SONAR (sound navigation and ranging)uses ultrasonic waves to detect and locate objects under water. In asubmarine equipped with a SONAR the time delay between generation ofa probe wave and the reception of its echo after reflection from anenemy submarine is found to be 77.0 s. What is the distance of theenemy submarine? (Speed of sound in water = 1450 m s–1).
An ultrasonic wave of frequency 45000Hz sent ot by a SONAR sows a frequency rise of 6ooHz on reflection from an aproaching submarine.If speed os sound in water is 1500m/s czlculate speed of submarine.
