Document Summary
Phys1070: intro physics for life sci - lecture 13: lens system review. Q: the cornea consists of 2 spherical surfaces very close together with the same radius of curvature, r=8. 0mm. Its power is the sum of the powers of the surfaces taken individually; p= Use subscripts cor" for the cornea and aqn" for the aqueous humour. = (1. 34-1. 00) / 0. 0080 = 42. 5 = 43 diopters. Object distance (p) is positive when the direction from the optical surface to the object is against the flow of light. Image distance (q) is positive when the direction from the optical surface to the object is with the flow of light. Radius of curvature (r ) is positive when the direction from the optical surface to the centre of curvature of the surface is with the flow of light. M is positive when the image is erect (same orientation up" as the object )
