12. It is the reflection of light that allows us to see things. Look around you.
What you see in general is light reflected from walls, ceiling, floor, and other
objects. Of course, there must be one or more sources of light present. These
sources are generally lamps or the Sun. if you are in a dark room, then there
is no reflected light, and the room is black. At night in a lighted room a
transparent windowpane serves quite well as a mirror. Yet during the day we
see through it, because transmitted light during the day masks the reflected
light. We often see beautiful reflections in nature.
