Refraction of Light
Step 1. Questions
Light bends, or refracts, as it passes from one medium to another. This is why a pencil or straw may appear bent or broken when it sits in a glass of water.
Refraction is also quite useful. The lenses in your eyes use refraction to focus images. If you wear eyeglasses, they refract light to help you see better.
For this e-Journal project, you will report on the refraction of light. Here are some questions to help guide your research.
Are you ready? Begin by visiting the Web sites listed in Step 2. Write down what you learn in the note-taking boxes. You may also use search engines to research refraction and lenses, or visit the local library.
- What are some types of lenses? What do they do to light that passes through them?
- What devices use lenses? What do these devices do?
- Does Earth’s atmosphere refract sunlight? If so, how?
- What are the parts of the eye? How do these parts work together to help you see?
- What questions do you have about the refraction of light and its uses?
When you are ready, follow Steps 3 and 4 to write your report.
Step 2. Research
