  • Thin Lens Equation
    An equation used to find the image location and height for images produced by thin lenses.
  • Ray Diagrams
    Diagrams used to find qualitative information about images formed by lenses or mirrors.
  • Radius of Curvature
    The radius of the imaginary sphere of which a lens's surface is a part.
  • Converging Lens
    A lens that is thickest in the middle and causes light rays to converge.
  • Diverging Lens
    A lens that is thinnest in the middle and causes light rays to diverge.
  • Focal Length
    The distance from the lens to the point where parallel rays converge or appear to diverge.
  • Magnification Equation
    An equation identical for mirrors and lenses, used to determine image magnification.
  • Lens Maker Equation
    An equation that calculates the focal length of a lens based on its shape and refractive index.
  • Index of Refraction
    A measure of how much a material slows down light, affecting the lens's focal length.
  • Plano Convex Lens
    A lens that is flat on one side and convex on the other.
  • Bi-Convex Lens
    A lens that is convex on both sides.
  • Bi-Concave Lens
    A lens that is concave on both sides.
  • Plano Concave Lens
    A lens that is flat on one side and concave on the other.
  • Real Image
    An image formed where light rays converge, typically inverted.
  • Virtual Image
    An image formed where light rays appear to diverge, typically upright.
