Visible Light
Read this text:
Dakota gazes out of the window of her bedroom. She sees a blue sky full of white clouds and bright green trees. Visible light allows Dakota to see all of the materials and colors in her surroundings. But why can Dakota see through some materials and not others? Some materials transmit light, or allow light to pass through them, while others do not. Objects can transmit all, some, or none of the visible light that they interact with. Click on the buttons below to learn more about how different materials transmit light.

When a person sees sunlight, it appears to be solid white in color. However, visible white light is actually made up of all of the colors in the rainbow. When different materials interact with white light, they appear to be different colors.
The color of a material depends on what happens to white light when it strikes the material. For example, the red petals on the flower in the picture reflect red light and absorb all other colors of white light. Meanwhile, the green leaves reflect green light and absorb all of the other colors in the white light.

White and black materials interact with visible light differently. Opaque white materials reflect all of the white light that strikes them, while opaque black materials absorb all of the white light.
For example, the white snow reflects all of the colors contained in white light, while the black road absorbs all of the colors contained in white light.
Time to Practice- use the colored arrows to accurately represent how light interacts with different objects.

Word | Definition |
| Cord that allows signal to travel from the eye to the brain |
| The inside back of the eye that contains specialized cells to convert light into an electrical signal |
| Colored part of the eye that controls the size of the pupil |
| Hole that allows light to enter the eye |
| Sits behind the pupil that transmits light onto the retina |
| Clear Protective layer that refracts light as it enters the eye |

Nearsighted-Farsighted
Due to the complexity of the eye, there are many things that can affect how well a person’s vision works. Nearsightedness causes a person to see nearby objects more clearly than distant objects. It occurs when a person’s eye is too long, or when the cornea is overly curved. This causes the lens to focus the image in front of the retina rather than on the retina.
Farsightedness causes a person to see distant objects more clearly than objects that are nearby. It occurs when a person’s eye is too short, or the cornea is not curved enough. This causes the image to focus behind the retina instead of on the retina.
