a) Calculate the focal air distance of a thin biconcave lens (n1 = 1.6) with radii of 20 cm and 20 cm (check the sign that corresponds to the radii of curvature). Locate and describe the image of an object to i) 40 cm from the lens, ii) 20 cm from the lens, iii) 10 cm from the lens, iv) -10 cm from the lens and v) - 40 cm from the lens. b) A double-convex lens is made of glass with n = 1.65. One of the faces has the radius of curvature equal to twice the radius of curvature of the other face. If the focal length of the lens is 20 cm, what are the radii of curvature?

The cornea behaves as a thin lens of focal length approximately 1.80 cm , although this varies a bit. The material of which it is made has an index of refraction of 1.38, and its front surface is convex, with a radius of curvature of 5.00 mm . (Note: The results obtained here are not strictly accurate, because, on one side, the cornea has a fluid with a refractive index different from that of air.) Part A: If this focal...
