Refraction Of Light I: Refraction Of Light I Refraction is the bending of light as it
passes from one transparent material
to another.
Slide16: Refraction Of Light II Light coming into a Convex Lens is
REFRACTED and comes together at a
point called the Focal Point. If you look at something through a Convex
Lens, it will look BIGGER than it really is!
