1 Geometrical Optics 3 Images Formed by Refraction: Lenses Images Formed by Refraction: generic case Rays originate from the object point, O, refract at the boundary and go to image point, I Real images are rmed on the side formed on the side opposite from the object 6 Cases of Figure 4: rays shown are schematic

Increase the radius of curvature . 4. Increase the object distance s . 20 Ex: A glass sphere has radius 25 cm, with n = 1.5. An bubble is 15 cm below the surface. How far below the glass surface does the bubble appear to be? Ex: A glass sphere has radius 25 cm, with n = 1.5. An bubble is 15 cm below the surface. How far below the glass surface does the bubble appear to be? Ex: A fish is in a spherical bowl of radius 15 cm. A cat’s nose is 10 cm from the bowl. Where is the image of the cat’s nose, and what is its magnification? (ignore the glass of the bowl) n water = 1.33
