Convex Lens
A convex lens is made from a transparent material that bulges outwards in the middle on both sides. It can focus light so that appears to meet at a single point, called the focal point. Light is refracted as it passes into, then out of, the lens.
Convex lenses are found in:
- magnifying glasses
- spectacles for people with long-sight (who can see distant objects clearly but not nearby ones)
- telescopes
