Experimenting with Light

Science is at  work all around us. To understand how these scientific principles work all we need to do is take a better look at things around us. Shiny spoons reflect light. This can teach us about the nature of light. If we look at a dull spoon the light does not get reflected that well. This teaches us about the nature of metal.

Mirrors reflect images if there is light in the room. If it is dark the same mirror becomes a playground of dark shadows. This teaches us that light is needed to reflect images in a mirror. In fact the image that we see in the mirror is nothing more than light waves reflected back at us from our body.

Sunlight is great for all kinds of experiments. Ever try lighting a pile of straw with a magnifying glass? If you don’t hold the magnifying glass at the right angle you can spend the full day trying to get a spark going and not get anything. There is science hiding in that as well.

Artificial light is the kind that lights up the insides of our homes. Of course it is not limited to being inside buildings, there are artificial light street lights out on the road as well. These lights are of many different kinds and each uses different scientific principles in generating light.  Besides light there are emissions of many other kinds in our universe.
