| Introduction:
While walking toward
the pool, I noticed that the pool seems deeper as I get
closer. I tried that a few times and it seems the bottom
of the pool is raising as I walk away. I was wondering
why this happens so I decided to do some experiments of
my own. I filled up a clear glass cup with water and
looked at it from the top and from the sides. It
happened again. Just to make sure, I dropped a coin in
the cup and I was able to see 2 coins while looking from
the sides.
These observations
gave me the idea of using this subject as my science
project. I want to know why the bottom of a cup or pool
seems to be raising when we look at the water surface
from an angle.
What happens to the
light when it passes through water?
