Oliver pours 5 grams of sugar into glass 1. As a result, the image of the pencil appears to be broken. Conversely, the less water placed in the glass, the higher-pitch the sound. An aquarium filled with water (n = 1.33) has flat glass slides whose index of refraction is 1.53. Save. Look through the glass from the front and observe the arrow. Its large and at an angle, so in other words the pencil under water doesn't line up with the pencil above water. C makes the water in the glass evaporate. The glass is sad because it's empty. If water is replaced by another liquid which is optically more dense than water, then the bending of the pencil will increase.

The refraction causes an apparent shift in the position of the part of the pencil within the water. The diagram explains this better. In the experiment that you just completed, light traveled from the air, through the glass, through the water, through the back of the glass, and then back through the air, before hitting the arrow.

Experiment with your own special sounds by turning glasses of water into instruments, make some cool music and find out how it works. D reflects the pencil on the water's surface. As light enters water at an angle, it bends away from its original path, and this makes the image look bent. Hit the glass with the least amount of water and observe the sound, then hit the glass with the most water, which makes the higher sound? A pencil placed in water appears to be bent because of refraction of light. When the arrow is moved to a particular distance behind the glass, it looks like it reversed itself. Try using differently shaped glasses. Where the light all comes together is called the focal point, but beyond the focal point the image appears to reverse because the light rays that were bent pass each other and the light that was on the right side is now on the left and the left on the right, which makes the arrow appear to be reversed. This is because the optically denser medium will cause more refraction of light rays. Put the note card behind the glass of water and slowly move the note card back. Only 2 colors used, black and white. Just because light bends when it travels through different materials, doesn't explain why the arrow reverses itself.
