1. 1. http://www.physics.metu.edu.tr/~bucurgat/ntnujava/Lens/lens_e.html
2. 2. <ul><li>The image of an object 18 cm from a convex mirror is half the size of the object. What is the focal length of the mirror? </li></ul><ul><li>A concave shaving mirror is constructed so that a man at a distance of 20.0 cm from the mirror sees his image magnified 1.50 times. What is the radius of curvature of the mirror? </li></ul>
3. 3. <ul><li>A dentist holds a concave mirror whose radius of curvature is 40.0 mm at a distance of 15.0 mm from a tooth to view a small circular cavity 2.00 mm in diameter. How large is the image of the cavity? </li></ul><ul><li>A dentist uses a spherical mirror that produces an upright image that is magnified four times. What is the focal length of the mirror in terms of the object distance? </li></ul>
4. 4. <ul><li>An object is placed 40.0 cm from a screen. At what point between the object and the screen should a converging lens with a focal length of 10.0 cm be placed so it will produce a sharp image on the screen and what is its magnification? </li></ul><ul><li>A stamp collector views a stamp with a magnifying glass. If she sees the stamp magnified by a factor of 2.5 when the glass is held 3.0 cm from it, what is the focal length of the lens? </li></ul>
5. 5. <ul><li>An object is placed 0.40 m in front of a converging lens, which has a focal length of 0.15 m. If a concave mirror with focal length 0.13 m is placed 0.50m at the back of the lens, where is the final image formed and what are its characteristics? </li></ul><ul><li>The objective lens and the eyepiece lens of a compound microscope have focal lengths 2.8 mm and 3.3 cm, respectively. If an object is placed 3.0 mm from the objective lens, where is the final image located? </li></ul>
