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?
