    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,...

    18. A thin lens made of glass with the index of refraction versus wavelength as shown in the figure. It has a focal length of magnitude 10.0 cm for green light. You shine a second laser light on the lens and find that the focal length now has a magnitude less than 10.0 cm. What color 1.545 could be the second laser? a. red b. blue c. also green d. It depends on whether the lens is converging or diverging...

    A "biconvex" lens is one in which both surfaces of the lens bulge outwards. Suppose you had a biconvex lens with radii of curvature with magnitudes of |R1|=10cm and |R2|=15cm. The lens is made of glass with index of refraction nglass=1.5. We will employ the convention that R1 refers to the radius of curvature of the surface through which light will enter the lens, and R2 refers to the radius of curvature of the surface from which light will exit...

    The figure below shows a thin converging lens for which the radii are R1 = 9.70 cm and R2 = -10.7 cm. The lens is in front of a concave spherical mirror of radius R = 7.32 cm. If its focal points F1 and F2 are 4.96 cm from the vertex of the lens: a) Determine its index of refraction. b) If the lens and mirror are 21.3 cm apart and an object is placed 8.63 cm to the left...

    The figure illustrates qualitatively a corrective lens of -2.75 diopters. R 8.46 cm The lens material is CR-39 monomer, with an index of refraction of 1.499. Calculate R, the radius of curvature of the outer surface for the lens. Note: the diopter is a measure of the refractive power of a lens, and equals the reciprocal of the focal length in meters. (Example: for +3 diopters, f=0.333 meters.) -18.54 cm Submit Answer Incorrect. Tries 4/12 Previous Tries
