Optics: Reflection and Refraction

When we see objects around us, we do not sense them directly. Rather, what we see is light that has first struck the object in question and has then reached our eyes. At the same time, objects might appear distorted under some circumstances, as if the reflected light didn't reach our eyes directly, but encountered some sort of interference first.
