No, a mirror is not a light source.
Mirrors reflect light, they do not produce it.
Here's why:
- Light sources generate their own light. Examples include the sun, a light bulb, or a fire.
- Mirrors simply bounce light that hits their surface. They change the direction of light but don't create new light.
Think of it this way: If you shine a flashlight on a mirror, the mirror will reflect the light back at you, making it appear brighter. However, the mirror itself doesn't create the light. It's still coming from the flashlight.
