because there is no friction between pencils and glass and glass is harder than the lead in the pencil .and glass surface is smoother than the surface of paper

What does a refracted image look like?
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.
