Focal Length - F.L. = 1 / Diopter Diopter = 1 / F.L (meters) Prism - Δ = Diopter / Meters Diopters = Δ * Meters Meters = Diopters / Δ Prentices Rule - Δ = (Diopters * decentration (mm)) / 10 Diopters = (Δ * 10) / dec (mm) dec (mm) = (Δ * 10) / Diopters

Due to refraction a prism bends light rays toward the ___________of the prism? - Base What is P=C/D ? - P = Prism C = the displacement of the object in cm D = the distance between the prism and the virtual image in meters This formula explains the relationship between the power of prism and the ability to bend light. Two Prisims base-to-base form what type of lens? - Plus or Convex
