Today in class we went into depth about refraction and
reflection. We were shown multiple demos that helped us to understand how light
is affected when moving between mediums of different "speeds". For
example, when light passes through air into water, the reflection will be bent
because air is a faster medium compared to water. At first this was really
confusing and mind boggling, but after practicing these concepts through
worksheets and Once I got home, as I was drinking a glass of water, I decided
to use a straw to apply what I had learned in class today. As you can see from
the picture below, the straw looks like it is bent, yet common sense tells us
its not. Because air is a faster medium compared to water, the ray of light
(that allows us to see the straw) bends closer to the normal, perpendicular
path of light. Because of this, the straw looks bent when it is really intact.
