Problem 1 – A light ray travelling in a thick piece of glass (n = 1.52) that is sitting in air strikes the air/glass interface at an angle just greater than the critical angle, so h h i ll i ll fl d If l f i h d that the ray is totally internally reflected. If a layer of water is than poured on top of the glass sheet, will the ray still be totally internally reflected?

Problem 2 – While doing your physics homework in the library late one night, you notice the image of the desk lamp reflected from the varnished (n = 1.47) table top. When you put on your polarized sunglasses you notice that the reflected image When you put on your polarized sunglasses, you notice that the reflected image completely disappears. What is the angle of incidence at which the light is striking

Unformatted text preview: Problem 3 – A lens produces a real image that is twice as large as the object and located 15 cm from the lens. What kind of lens is this? What is the focal length of e ns? hat e bject istance? the lens? What is the object distance? Problem 4 – A lens has a focal length of ‐ 32 cm. What kind of lens is this? Find the image distance and magnification that results when an object is placed 23 cm in ont f is ns front of this lens. Problem 5 – Given the compound lens system below, use a ray diagram to find the approximate location of the image. Then use the thin lens equation and find the istance om e cond ns e nal age distance from the second lens to the final image....
