Light Bounces Off Objects

What will we be learning today?

  • In this lesson, we are going to learn all about how does light bounce off objects.

  • How Does Light Bounce Off Objects?



    Review how any visible object must either give off its own light or reflect light from another light source. We can picture how light reflects (bounces) off objects using light rays as in the diagram.


    How is light reflected by a mirror? When a ray of light reaches your eye from a mirror, where did the light come from before it struck the mirror?




    The angle between an incoming light ray and a surface equals the angle between the reflected light ray and the surface. This is called the law of reflection.



    Ambulance signs are often done in "mirror writing" so that they read correctly when seen in a rearview mirror.


    Light rays that bounce off polished, shiny surfaces can reflect a "picture" of the light source, called an image. The things you see when you look in a flat mirror, for example, look very real, almost as if they existed on the other side of a window. However, your experience tells you they are not real-they are just images of the real things in your world. The picture shows how flat mirrors form images.



    Whom does each student see when he or she looks in the mirror?
