Light Through Convex and Concave Lenses

Understand how convex and concave lenses bend light and form images through refraction experiments.

What you need

• Convex lens (magnifying glass can be used)
• Concave lens (optional, or borrow from a school science kit)
• Flashlight or sunlight
• White paper or notebook
• Pencil

How it works

A convex lens converges light rays, forming a real, inverted image on the opposite side. A concave lens diverges rays, producing a virtual image. These principles are foundational in understanding lenses in spectacles, cameras, and microscopes.
