Create a model illustrating light passing through converging and diverging lenses with a variable focal distance.

Project Overview
Develop an interactive simulation demonstrating how light rays bend through converging and diverging lenses. Users should understand the impact of lens curvature on light paths.

UI/UX Design and Flow
- Design a clean interface displaying converging and diverging lenses side by side.
- Incorporate sliders or draggable elements for users to adjust the focal distance of each lens.

Core Functionality and Logic
- Animate light rays passing through lenses, showing real-time adjustments as focal distances change.
- Accurately illustrate bending angles to visually differentiate the effects of converging versus diverging lenses.

Best Practices
- Ensure smooth interaction and immediate visual feedback as users alter focal distances.
- Clearly label lens types and provide brief tooltips explaining converging and diverging behaviors.
- Maintain consistent styling for a professional appearance with a focus on educational value.

Q: What specific properties of the lenses do you want to illustrate?
A: The bending of light rays at different angles

Q: How do you want the user to interact with the model?
A: Allow users to drag and change the focal distance
