Light
Light
It's all around us! And it moves and behaves in different ways!
Reflection occurs when light bounces off objects. How much reflection depends upon how even the surface is. If the surface is rough, the light scatters. If the surface is smooth and flat, the light will bounce off it at equal angles. That is why a flat mirror reflects a good likeness of the object being reflected.
Look at the diagrams. Notice the angles at which the rays of light strike the surfaces.
Refraction occurs because light bends. A lens is a piece of transparent material. It is usually made of glass and has at least one curved surface. Look at the convex and concave lenses below.
The curved surface/surfaces of a lens bends the light. Notice the paths of light of the convex and concave lenses shown below.
