Echolocation is the ability to locate a distant or a concealed object by sound waves off of the object. This is done by measuring the time taken for an echo to return and calculating the direction the echo came from. For example, a bat can send ultrasonic waves of the insect.navigationlocation of objectsmedicineUltrasoundDoctors use ultrasound waves to look inside the human body. Ultrasound waves enter the body and off of internal organs. An ultrasound device uses the to make a picture called a sonogram. Sonograms can be used to treat medical conditions, as well as to examine developing babies.depth = velocity x timespeed of soundin waterfor wave to hit barrierand returnSonarSonar stands for sound navigation and rangingdepth of water, maplocate objects such as sunken ships. A sonar device sends a burst of ultrasound waves downward through the water. The waves strike a barrier, such as a sunken ship, and are back. The device detects the waves and records how long it takes for the original wave to leave and return. A computer uses the speed of sound in water and the time for the wave to make a round trip to calculate the depth of the object. © Copyright NewPath Learning.
