5. Show that the power of a system changes when it is reversed (by rotating it by 180o about an axis normal to its optical axis) unless the refractive indices of its object and image spaces are equal. Consider a thin lens of refractive index 1.5 and radii of curvature 10.0cm and -15.0cm with air in its object space and water in its image space. Calculate its focal lengths and power, then reverse the lens and repeat the calculations

5. For a thin positive lens made from a dielectric of refractive index n, find the ratio of the radii of curvature of the two surfaces (i.e. R\lR2) such that the angular deviation, Ay, for a ray from an object at infinity (ie.- incident ray parallel to the optical axis) is the same at both faces of the lens.

Optics and Converging & Diverging Lenses 1. What is the relationship between the curvature of a lens (thick vs thinner converging lenses) and its light-bending power? 2. Focal length: is there a trend in the image distances vis a vis focal lengths as the object distance gets larger? What happens to the thin lens formula when object distance is very large? 3. In the compound lens formula, 1/fcomp = 1/f1 + 1/f2, why does a longer focal lens will not...

An object placed 20 cm in front of a lens results in an image being formed 24 cm behind the lens. Each surface of the lens is convex (bulging away from the optical plane) with the same radius of curvature, and the index of refraction of the glass composing the lens is Tiens =1.4. What is the radius of curvature of either side of this lens (to the nearest tenth of a cm)? Note, once again, the focal length of...

The crystalline lens of the human eye is a double-convex lens made of material having an index of refraction of 1.44 (although this varies). Its focal length in air is about 8.00 mm , which also varies. We shall assume that the radii of curvature of its two surfaces have the same magnitude. (Note: The results obtained in the parts A, B and C are not strictly accurate, because the lens is embedded in fluids having refractive indexes different from...
