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...

Which type of testing determines the retinas ability to detect subtle differences in brightness or shading between targets and their backgrounds? - Contrast Sensitivity testing Which machine uses laser lights in a pattern of stripes in which the patient indicates the orientation of the stripes? -...

Every camera includes the following elements: a.) Aperture, shutter, film b.) Lens, film, diaphragm c.) Camera body, lens, frame counter d.) Aperture, camera body, film - D. A good camera lens system will: a.) Effectively focus on an image at any distance b.) Have the same focal length for al...

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
