Answer:
Ultrasound monitoring of fetuses and mapping the seabed are similar in that they both use sonar technology to create images.
Step-by-step explanation:
Ultrasound monitoring uses high-frequency sound waves to create images of the developing fetus inside the womb. The sound waves are sent out by a transducer and are reflected back to create an image of the fetus, similar to how sonar sends out sound waves and receives the echoes to create an image of the seabed.
Mapping the seabed uses sonar technology to create images of the seafloor. Sound waves are sent out by a transducer and are reflected back by the seafloor, creating an image of the seabed. The time it takes for the sound waves to return is used to determine the depth of the seafloor.
Both ultrasound monitoring and mapping the seabed use the principle of echolocation, which is the ability to locate objects by reflecting sound waves off them and measuring the time it takes for the echoes to return.
In summary, both ultrasound monitoring and mapping the seabed use sonar technology to create images by sending out sound waves and receiving echoes, which is the principle of echolocation.
