→About Convex Lenses
: A '''convex''' [[lens]] is used to [[focus]] [[light]].
: Projecting an [[image]] onto a [[screen]] using a '''convex [[lens]]''' creates a [[Real Image|real image]]. Looking through a '''convex [[lens]]''' the [[image]] seen is a [[Virtual Image|virtual image]].
: When the [[Object Distance|object distance]] is greater than the [[Focal Length|focal length]] of a '''convex [[lens]]''' the [[image]] produced is [[diminished]] and [[inverted]] (upside down and back to front).
: When the [[Object Distance|object distance]] is less than the [[Focal Length|focal length]] of a '''convex [[lens]]''' the [[image]] produced is [[magnified]] and the right way up.
