Solution

The correct option is A
SONAR

The technique which uses ultrasonic waves to measure the distance, direction and speed of underwater objects is known as SONAR. SONAR stands for Sound Navigation and Ranging. RADAR is an object-detection system that uses radio waves to determine the range, angle, or velocity of the object. Echocardiography or echo is a painless test that uses sound waves(ultrasound) to create moving pictures of your heart. Ultrasonography is a technique that uses echoes of ultrasound pulses to delineate objects or areas of different density in the body.

An automatic focus camera is able to focus on objects by use of an ultrasonic sound wave. The camera sends out sound waves that reflect off distant objects and return to the camera. A sensor detects the time it takes for the waves to return and then determines the distance an object is from the camera. If a sound wave returns to the camera 0.150 seconds after leaving the camera, how far away is the object? (take speed of sound = 330 m/s)
