Common Questions and Their Answers in the Gizmo
1. How does changing the object distance affect the image formed by a convex lens?
When the object is moved closer to the convex lens, the image generally becomes larger and moves further from the lens. Conversely, moving the object farther away results in a smaller, real image closer to the focal point. The answer key explains that the position of the object relative to the focal length determines whether the image is real or virtual, upright or inverted.
2. What is the significance of the focal length in the ray tracing lens simulations?
The focal length is a critical parameter that influences how light rays converge or diverge after passing through the lens. A shorter focal length produces a more powerful lens with a greater bending effect, resulting in a different image size and position compared to a lens with a longer focal length. The answer key clarifies these relationships with diagrams and explanations.
3. How do concave lenses differ from convex lenses in ray tracing diagrams?
Convex lenses converge light rays to form real, inverted images, while concave lenses diverge rays, producing virtual, upright images. The answer key highlights these differences through illustrative ray diagrams and emphasizes the importance of understanding how each lens shape affects light paths.
