HFOIUVGEUIBVFBEVMy Hypothesis: Can light reflect through water? Materials: (1) 1 Clear plastic soda bottle, 2 liter and cap (2) 1 deep sink or large pan (3) 1 sharp nail and hammer (4) source of light, flashlight (5) water Procedure (1) Empty the bottle. Fill the bottle with water up to the brim and seal it with the cap. Punch a hole into the side of the bottle with the hammer and nail (2) Place the bottle at the edge of a sink and loosen the cap so the water flows. (3) Shut off the water flow and shine a bright, beam of light through the bottle. Let your helper kill the lights in the room and loosen the cap. (4) Place your hand under the stream and slowly lift it up so you can see a tiny spot of light on your finger.
Observation and conclusion: The light was bouncing around inside the stream of water. The light bouncing is called total internal reflection, although in my model it's not exactly "total." My light source is probably not powerful enough, and even if it were there would be little light down the stream that's why I started low in the shadow of the sink and slowly raise my finger. The closer I got to the bottle level, the more light I saw bouncing around in the water. Our Telephone Company, cable TV outlet, or Internet service providers use this scientific law. They use to give information fiber optic cables, and this is how it works. A laser beam carries our telephone conversations and information.
It's fired into one end of the cable where all the beams bounce off the cable's walls just like the light in the water stream. When it comes out it's traveling with the speed of light. BBVUDBUOB.
