Fundamentals of Physics Exam 4 | Questions and Answers Sonar is a technology used to make maps of the sea floor, as well as to find fish and military targets. Sonar is very similar to medical ultrasound, in that it makes images using sound, but the sonar device is attached to the bottom of a boat and projects downward through the water. While medical ultrasound uses frequencies in the MHz, sonar works best with lower frequencies, because it has to travel longer distances. Calculate the wavele...
