A lens with two convex surfaces, both with radii of curvature of 0.25 meters, is used to focus light. If the lens is made of crown glass, it would have an index of refraction for red (656 nm) light of 1.509 and for blue light (486 nm) of 1.517. What happens when it is used to make an image of a distant source of white light? Pick those that apply. The red light focuses closer to the lens than the blue light. The blue light focuses closer to the lens than the red light. The red light falls in a cone outside the blue light as it the light converges to a focus, so when blue is in focus there is a fuzzy red ring around it. When the red light is in focus it is surrounded by a blue halo.

A patient with a refractive myopia cannot see objects clearly if they are further away than 10 m. To be able to drive safely and obtain his driving license, he needs to be able to clearly see objects up to 100 m away. In this problem, Pmin eye = minimum optical power of the patient’s natural eyes, Pmin combo = minimum optical power of the patient’s natural eyes + corrective glasses, and Pmin glasses = minimum optical power of the corrective glasses. Calculate the focal length.
You are studying a rare species of small mushroom by growing them in a large tank filled with a 60percent glucose solution, which has an index of refraction of ns =1.44. In order to magnify the small mushroomsample, you have built a long glass rod with curved ends which you insert into the top of the tank. The glassrod has an index of refraction of ng =1.55. The lower curved end of the glass rod is 12cm above the mushroomsample, and its magnitude of curvature is |r1| = 6cm. The length of the glass rod is d = 25 cm, and the uppercurved end has a magnitude of the radius of curvature of |r2| = 10cm. The signs of both radii of curvature are leftto the student to determine from the figure below. The index of refraction of air is, as always, 1. Carry a largenumber of significant figures through the problem and simplify at the end.(a)Compute the final location of the image formed of the mushroom by the device.(b)Compute the total magnification of the glass rod.

Create a ray diagram for eyeglasses that contain a diverging lens. Assume you are looking at a 2 cm tall object that is 4 cm from the lens. The focal length is 3 cm. What type of vision are they used to correct? Give both names. How do they do this? Explain.
A small pin fixed on a table top is viewed from above from a distance of 50cm. By what distance would the pin appear to be raised if it is viewed from the same point through a 15cm thick glass slab held parallel to the table? Refractive index of glass = 1.5. Does the answer depend on the location of the slab?
