Questions for Discussion: Refraction of Light Demonstration
- According to your observations, what happens to the beam of light when it hits the rectangular glass prism? When it exits?
- How does the direction of light before it hits the rectangular prism compare to its direction after it exits?
- Why do you think the rays bend after entering the lens? Why do you think they bend after leaving the lens?
- How do the shapes of these transparent objects affect light passing through them?
- Use a ray diagram to explain your observations. How might you use lenses in practical applications?
