How is Light Reflected?

Today we learned about light and the different ways light can be transmitted. In case some of you left class today without grasping all the concepts I have outlined the main ideas. I encourage all of you to explore the link below which builds on today's lesson.

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.


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 following link will direct you to the Bill Nye the Science Guy website. There is a video on light optics, bending, and bouncing that I think all of you should take the time to watch because it will build on today's lesson. Enjoy!
