A biconvex lens has two distinct radii of curvature. One face has a radius of curvature of magnitude R, = 11.8 cm, and the opposite face has a radius of curvature of magnitude R, = 18.9 cm. The lens medium has an index of refraction of n = 1.48. (a) Calculate the focal length (in cm) of the lens for light incident on the side with radius of curvature R,. cm (b) Calculate the focal length (in cm) of the...
A typical human lens has an index of refraction of 1.430. The lens has a double convex shape, but its curvature can be varied by the ciliary muscles acting around its rim. At minimum power, the radius of the front of the lens is 10.0 mm, whereas that of the back is 6.00 mm. At maximum power, the radii are 6.50mm and 5.5mm, respectively. If the lens were in air: What would be the maximum power and associated focal length...

Review Constants In this example, we will apply the thin-lens equation to a lens that has two concave surfaces. The two surfaces of the lens shown in (Figure 1) have radii of curvature with absolute values of 20 cm and 5.0 cm. The index of refraction is 1.52. What is the focal length f of the lens? SOLUTION SET UP AND SOLVE The center of curvature of the first surface is on the incoming side of the light, so R,...
