What Does a Plant Sound Like?The article reports Yossi Yovel and his colleagues have developed a computer algorithm that can identify some plant species by their unique sonar echoes. The algorithm is based on echolocation, a process used by bats the find their food. From this algorithm, Yovel...
FEMALE STUDENT: Well, bats—since they're all blind, bats have to use sound for—uh, y'know—to keep from flying into things. FEMALE PROFESSOR: That’s echolocation.Echolocation is pretty self-explanatory: Using echoes—reflected sound waves—to locate things…As Carol said, bats use it for...
the section of the brain called the visual cortex does not become useless for them. _(5)_ As Underwood said in an interview, "I can hear that wall behind you over there. I can hear right therehe radio, and the fan." Through echol...

Echolocation: This topic refers to research on the biosonar of marine mammals or bats. Electrolocation: This topic includes research on active and passive electrolocation. In contrast to passive electrolocation in which animals perceive electric fields emitted from surrounding organisms, active electrolo...
So sound travels faster through water than it does through air. So what happens when a sound wave? um, okay,you've got a sound wave traveling merrily along through one medium, when suddenly it hits a different medium. What's gonna happen then? Well, some of the energy is gonna be ...
