How can you quickly determine the focal length of a converging lens? Will the same method work for a diverging lens?
Answer to relevant QuestionsHow would you use a converging lens as a magnifying glass? Can you do the same with a diverging lens? How can the focal length be quickly determined experimentally for a concave mirror? Can you do the same thing for a convex mirror? An object is placed 50 cm in front of a convex mirror and its image is found to be 20 cm behind the mirror. What is the focal length of the mirror? What is the lateral magnification? A virtual image of magnification +2.0 is produced when an object is placed 7.0 cm in front of a spherical mirror. (a) The mirror is (1) convex, (2) concave, (3) flat. Explain. (b) Find the radius of curvature of the ...A child looks at a reflective Christmas tree ball ornament that has a diameter of 9.0 cm and sees an image of her face that is half the real size.
