Ultrasound and Magnetic Resonance Imaging (MRI), are technologies used to create images of a patient's internal features. In many instances, either technology can be used when diagnosing patients. However, ultrasound is often preferred for diagnosing moving features, while MRI is often preferred for diagnosing features surrounded by air or dense bone. Based on these differences, which of the following best describes the waves used by these technologies?

sonar - device which is used to find the submit submarines, sankalp ship. sonar waves consists of a transmitter and detector which are installed in the observation centre on board of a ship. the ultrasonic waves are sent into the sea at high frequency about 1000 khz in all direction.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

magnets not strong enough
