Signed, Neil -Central Middle School. Even without mirrors, in order for us to see anything, we must have light. Light rays are constantly being made and emitted from light sources such as the sun or light bulbs. These rays project out in an infinite number of directions. They will continue to travel until they strike an object such as a cat, table, or even a piece of meatloaf.
Different objects respond differently.
Some are very reflective and appear shiny. Others absorb a lot of light and appear dull. How an object absorbs and reflects light defines its shape, color, and texture. Obviously the absorbed light stays with the object, but the reflected light scatters outward to find other objects. It rapidly becomes the most complicated game of pinball you could ever imagine.
