  4. Converging and Diverging Lenses Converging Lenses: Lenses that make parallel light rays come together (converge) Diverging Lenses: Lenses that make parallel light move apart (diverge)

  5. Converging Lenses We use three rays to draw a ray diagram for converging lenses. Rules: • Any ray that enters the lens parallel to the principal axis will pass through the focal point on the other side of the lens. • Any ray that travels through the centre of the lens will keep travelling in the same direction. • Any ray that leaves from the focal point will leave the lens parallel to the principal axis.
