The full moon doesn't actually produce its own light. It reflects sunlight. Here's how it works:

1. Sun's light: The sun emits light in all directions.

2. Moon's reflection: Some of this sunlight reaches the moon. The moon's surface is dusty and rocky, and it reflects a portion of that light back into space.

3. Our view: From Earth, we see this reflected sunlight as the bright glow of the full moon.

Think of it like a mirror: the moon is like a giant, slightly dusty mirror reflecting the sun's light towards us.
