If light diffraction is what you are asking, then the pencil looks a bit broken on the line where it passes from air to water. Also the pencil looks about one third bigger under water.
A pencil is seem to be croaked when put in water because,REFRACTIONoccurs.REFRACTION is a property of light which can be defined as this=the speed of light is different in different medium, it is slow in dense medium.It is fastest in vaccum.This shows that the light reaches faster in air and little slow in water this is the reason that the pencil seems little croaked in water
Take a pencil and a glass of water, and put the pencil in it. The apparent displacement of a pencil in the water is due to refraction, which is the change of direction of a wave as it moves from one medium into another.Light is being reflected off the pencil to allow us to see it. The light reflected off the part above water is propagated through air to our eyes. The part below the water must move through the water and then through the air for us to see it. As the light moves from the water into the air, it undergoes refraction, and changes direction. The part of the pencil below the water appears displaced to the viewer.
You will observe a pencil on a glass of water. Unless you're not looking that way, in which case, you will observe whatever you happen to be looking at. Unless, you're blind, in which case you won't observe anything.
The pencil appears bent because of "refraction". Simply put, light can't travel as fast in water as it does in the air. The difference in speed causes the image to appear to bend a bit. See the related link for more details.
Because when water ansd glass are put together and they are kind of work like a magnafine glass. ^^ what do you mean by glass..?
Refraction. Take a clear glass, pour some water in it, and put in the glass a pencil. It looks like the pencil breaks.
A Refracted image is like an illusion. Which fools the brain e.g. You see a pencil but the pencil has split in two parts.Demonstration:You will need: Glass, Pen or Pencil and WaterSteps:1. Put the glass on a table,2. Fill the glass to about 3/4 quarters of water,3. Put the Pen or Pencil in the glass of water,4. See what happens to the pencil.See, it seems to have split.
no thank you
put the pencil into a measuring jug filled with water to 100g the when you put the pencil in you see how much it has gone up . if it has gone up to 150g the pencil will the 50g in area. because you put in 100g of water
when you put water inside milk, the milk will look like what it did without water.
Refraction. It's basically the same reason a pencil put in a glass of water appears to be "bent".
An interesting property of light called refraction just took place. When light enters the water, it can't move as fast and it has to slow down slightly. It's kind of like how if you are walking, you can walk at a normal speed but if you walk in water, you can't walk quite as fast. If light from the image enters the water straight, then the image looks normal - which was what you originally did when the pencil was straight up and down. If the light enters the water at an angle, then the change in speed between the open air and water causes the light beam to bend away from its original path. When the pencil was at an angle, the image was at a bigger angle in the water than in the air and made the pencil look like it was bent.

it depends when you put it and depends that on how much you could put the water to what level it would be
it makes the egg float
put hands on cold water
John Pendry's team suggest that by enveloping an object in a metamaterial cloak, light waves can be made to flow around the object in the same way that water would do so. Professor Pendry explained:"Water behaves a little differently to light. If you put a pencil in water that's moving, the water naturally flows around the pencil. When it gets to the other side, the water closes up, a little way downstream, you'd never know that you'd put a pencil in the water - it's flowing smoothly again. Light doesn't do that of course, it hits the pencil and scatters. So you want to put a coating around the pencil that allows light to flow around it like water, in a nice, curved way.¨ So in effect what it would have to do is to hold on to the light waves allowing it to reassemble itself once it has passed the cloak.
