## Project Structure

The application is organized into:
- **Pages** (`src/pages/`) - Individual task simulations and the home hub
- **Components** (`src/components/`) - Reusable UI elements like charts, sliders, and navigation
- **Design guidelines** (`src/design-guidelines.js`) - Consistent styling and color schemes
- **Math functions** (`src/math_functions.js`) - Mathematical utilities for calculations

Each task provides an interactive environment for exploring the physics concepts covered in the British Physics Olympiad challenge, making complex optical phenomena accessible through visual simulations.
