SONAR  

Sound is also used to create the illusions in 3D space through the bouncing of sound waves.  It gives not only animals such as whales and bats an idea of where things are in three dimensional space, but it also is used by oceanographers to map out the bottom of the ocean. As opposed to photographs which are able to give the exact details of the real world, sonar is only useful on a macro scale because it is able to because it can give an idea of space because of the time and angle of the reflection of sound waves.
