A lens is made from glass with an index of refraction of 1.66 for violet light and 1.61 for red light. Both sides of the lens are convex with equal radii of curvature. For which color, violet or red, is the focal length larger? Explain how you know.
A certain thin lens is made of glass with refraction index nlens = 1.500. In air, where the index of refraction is 1.000, the lens has focal length f0 = 26.5 cm. What is the focal length f of the lens when immersed in oil, where the index of refraction is 1.460?
A certain thin lens is made of glass with refraction index ?lens=1.500. In air, where the index of refraction is 1.000, the lens has focal length ?0=15.5 cm. What is the focal length ? of the lens when immersed in water, where the index of refraction is 1.330?
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...

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...
