1. A concave mirror has a radius of curvature of 40 cm. An object is placed 70 cm from the mirror. Determine the nature, position, and relative size of the final image. SEE EXTENDED SOLUTION
2. A concave mirror has a radius of curvature 40 cm. An object is placed 15 cm front of the mirror. Determine the nature position relative size of the final image.
3. An object exists 100 cm from a curved mirror. A) We desire to have an image whose magnification is - 2. What kind of mirror is needed; what is its radius? B) We desire to have an image whose magnification is - 1/2. What kind of mirror is needed; what is its radius?
4. Two concave spherical mirrors have radii of 4.8 m. They are placed facing each other 10 m apart and sharing a common principal axis. An object is placed 4 m from the left-hand mirror. Locate the position of all the images formed by the system. Describe where you have to look to see the various images. Is it possible to devise a mechanism to see all the images at the same time?
5. We have an object 5 cm tall of which we wish to create a real image 2 cm tall and 100 cm from the object. What kind of mirror should we use? What should be its radius of curvature?
