What happens when you shine light in water?
Water affects light rays in a similar way. When a light ray passes from air into water a similar thing occurs: the light ray is bent as it strikes the surface of the water. This ‘bending of a ray of light’ when it passes from one substance into another substance is called refraction.
Why do images shift when looking through water?
It is an optical illusion, called refraction. Light only bends when it passes from a substance of one density into a substance of a different density—in this case from air to water. Next, trying seeing how the concave (turning inwards) surface of a spoon reflects the image upside down.
How do you investigate the refraction of light in water?
Instructions
- 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.
- Fill a glass with water.
- Slowly lower the piece of paper behind the glass of water.
- Look through the glass of water and watch what happens.
How do you demonstrate refraction of light?
Pour water into the glass jar, and place the jar in the center of the white paper. Turn off the lights in the room. From the outside of the box, face the flashlight at the two slits in the box’s side. Turn on the flashlight, and observe how the glass refracts the light that shines through the two slits.
What is refraction experiment?
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. This is the point at which the light from an object crosses.

Is the pencil actually broken?
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.
Why do pencils bend in water?
In this experiment, light first travels through the air – which is easy to move through – and then through the water, where it slows down. This change in speed causes the light to bend, or refract, meaning that the part of the pencil that is in the water will appear shifted.
Why does a pencil look bent in water?
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. At the boundary, this ray refracts.

What happens when you put a coin in water?
Light bends when it passes from one medium (water) into another medium of a different density (air). The light bends when it passes from water to air on top of the water. It does the same thing when it passes through the glass, making the coin appear to be closer to you. As a result, you see two images of the coin.

How long does it take to do a light experiment?
Similar to our Optical Illusion science experiment, light experiments also rely on what our eyes see. This quick experiment (actually 2) is so fun to do with kids, takes only 5 minutes and is SUPER EASY — all you’ll need is a pencil and a glass of water.
What happens to light waves when you shine a flashlight?
Let’s look at light waves without the pencil. Since both the glass and the water are more dense materials than air, when you shine a flashlight into the glass (on the left), the light waves will slow down slightly as they enter and then return to normal as they exist the other side so you see one round spot of light.
How to scatter particles in a glass of water?
This experiment replicates the scattering of small particles in the earth’s atmosphere in a glass of water, using a little bit of milk to scatter. A clear glass pitcher or tall jar with straight sides Milk (2% or Whole is best, or dry milk power) Fill a glass pitcher with water.
