| Getting a sneak peak at what
light is really made of
Light traveling
in a straight line appears colorless. But there's more to light than
just colorless nothingness. When light
passes through a wedge shaped piece of glass called a prism, the light is separated into 7
different and unique colors. You see these colors when light passes through rain or
moisture producing a rainbow.
- Place a mirror in the glass of water at an angle (let it lean
against the side of the glass).
- Turn the glass so the mirror is facing the sun.
- Hold the paper at a slant in front of the glass. Move the paper
around until you the rainbow colors. You may need to move the paper around slightly until
the colors come into full focus.
What you are seeing is the various wavelengths of light broken
apart. Sunlight is comprised of 7 different colors. A light bulb actually produces more
red and orange colors. A fluorescent light has more blue and yellow. |
