Sonar is a system that locates objects by transmitting sound waves and detecting the waves when they are reflected off of objects. Bats and many other animals, such as whales and dolphins, use natural sonar to navigate and capture
echolocation
It is called reflection. When objects reflect light, the light bounces off the surface of the object and into our eyes, allowing us to see the object.
Something called echo-location
Objects that don't give out light are called "non-luminous objects." These objects reflect light that falls on them, making them visible to our eyes.
Scientists that unearth and interpret objects from past societies are called archaeologists.
Objects that do not transmit light are called opaque objects. These objects absorb or reflect light, preventing it from passing through them. Examples include wood, metal, and concrete.

Objects that don't reflect light are called non-reflective or light-absorbing. These objects appear dark because they absorb most of the light that reaches them, instead of reflecting it. Examples include black velvet, asphalt, and some types of paints.
Those objects are called reflectors. They bounce light rays back in the direction from which they came.
An object's ability to reflect sunlight is called albedo. Albedo is a measure of how much of the sunlight that hits an object is reflected back into space. Objects with high albedo reflect more sunlight, while objects with low albedo absorb more sunlight.
a group of dolphins is called a school of dolphins.
