The broken pencil phenomenon occurs during your everyday spearfishing outing. A pencil part immersed in water looks bent due to refraction: the light waves from X change direction and so seem to originate at Y. Refraction occurs when light goes through a water surface since water has a refractive index of 1.33 and air has a refractive index of about 1. therefore making the pencil look Make sure the bowl is deep enough to demonstrate refraction. the pencil in the water. placed to the left of the cmter.

Micro Organisms We used a mason jar since all of our drinking glasses have an etched design in them. 98. A consequence of having different speeds in different mediums is that a ray of light bends when going from one medium to another. Bring your line of sight down to your shoulder and close one eye. That was a very cool magic trick. Light the glass or jar half way with This activity shows how a pencil in a half filled glass of water appears to be crooked or bent at the boundary of the water and air. It is designed to apply a load of 750 g ± 10 g to the tip of the pencil, where the angle of pencil against to the surface is fixed at 45º ± 1º. The pencil shaft is supported between the thumb and the middle finger and the forefinger rests on the top of the pencil shaft. Look at the pencil from the Wow. You'll often hear artists say that symmetry is boring, and this is simply because it makes things feel … Physics Snell’s law gives the relationship between angles of incidence and angle of refraction. water.
