How do you demonstrate refraction in water?


  1. Get a sheet of paper, and draw two arrows on it. One arrow near the top and one arrow near the bottom. Make the arrows point in the same direction.
  2. Fill a glass with water.
  3. Slowly lower the piece of paper behind the glass of water.
  4. Look through the glass of water and watch what happens.

How do you reflect a picture with water drops?

Basically you are placing a subject behind a drop of water and then using your macro lens to capture the refracted subject inside the drop. You can easily shoot these inside or if the conditions are right and you don’t mind laying in the wet grass, you can shoot them outside as well.

How does a pencil in water show refraction?

As you sight at the portion of the pencil that was submerged in the water, light travels from water to air (or from water to glass to air). This light ray changes medium and subsequently undergoes refraction. As a result, the image of the pencil appears to be broken.

What happens to the printed words when viewed through the drop of water in the plastic cover?

1. What happens to the printed words when viewed through the drop of water in the plastic cover? The printed words were magnified (as shown in Figures 1 & 2) when viewed through the drop of water in the plastic cover.

What do you see on the paper when the glass of water was exposed?

2. Hold the glass of water (being careful not to spill it) above the paper and watch as sunlight passes through the glass of water, refracts (bends) and forms a rainbow of colors on your sheet of paper.

Why do things appear bigger in water?

Light in Water Looking from above, an object under water appears larger than it does in air. It’s not that the image the light gave our eyes is bigger. It’s that the image is actually closer to our eyes, since the light is not passing straight down, but is instead bending relative to the water’s surface.

What happens when two drops of water meet?

Two drops of liquid, at first separate and distinct, meet and come together to form a bigger drop.

What is a water drop with refraction?

Water drop with refractions are normally seen on flowers and Leaves. But one can use anything, from needles to wires and pencils to obtain breath taking images. A small exquisite water drop is a world on its own.

How does refraction work?

How does this work? Refraction ( bending of light ) happens when light travels between two mediums. In the refraction experiment above light travels from the arrow through the air, through the glass, the water, the glass again and air again before reaching your eyes.

Is this light refraction experiment the most simple to set up?

This light refraction experiment might be one of the most simple to set up science experiments we’ve ever tried. It is a bit tricky to explain, but impressive even if you can’t quite get your head around it!
