# Question

An object 3.0 cm tall is placed at different locations in front of a concave mirror whose radius of curvature is 30 cm. Determine the location of the image and its characteristics when the object distance is 40 cm, 30 cm, 15 cm, and 5.0 cm, using

(a) A ray diagram and

(b) The mirror equation.

Use the mirror equation and the magnification factor to show that when do = R = 2f for a concave mirror, the image is real, inverted, and the same size as the object. A virtual image of magnification + 0.50 is produced when an object is placed 5.0 cm in front of a spherical mirror. (a) The mirror is (1) convex, (2) con-cave, (3) flat. Explain. (b) Find the radius of curvature of the ...A concave mirror is constructed so that a man at a distance of 20 cm from the mirror sees his image magnified 2.5 times. What is the radius of curvature of the mirror? For values of do from 0 to ∞, (a) Sketch graphs of (1) di versus do and (2) Mversus do for a converging mirror, (b) Sketch similar graphs for a diverging mirror. A converging lens with a focal length of 20 cm is used to produce an image on a screen that is 2.0 m from the lens. What are the object distance and the lateral magnification of the image?Post your question
