Study Notes
Mirror Types
- A key difference between a plane mirror and a convex mirror is their curvature, which affects the way they reflect light and images.
Convex Mirror and Light Sources
- In a torch, the source of light is positioned at the focal point of the convex mirror.
- In a projector lamp, the source of light is positioned beyond the focal point of the convex mirror.
