| Scientists have discovered that bats produce an ultrasonic wave during flight. This ultrasound wave is emitted through the mouth and nostrils. When it encounters an object, it is reflected and then transmitted through the mouth. the ears of the bat. After receiving the reflected ultrasonic waves, the bat's ears can correctly judge the distance between the target and itself. Therefore, if it is food, he will catch it, and if it is an obstacle, he will avoid it. This echo-based method of target detection is called “echolocation”. The bat's “echo locator” is a highly precise navigation instrument that allows the bat to fly unimpeded between the thin, taut wires. Scientists invented sonar based on the principle of echolocation. Using sonar systems, people can detect ocean depth and draw mapsgraphics thousands of meters underwater; Fishermen use sonar to get information about schools of fish in the water when fishing. |
