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!

Slide17: 

Today Refraction of Light in… …..Water …..A Lens Then……Class Test!
