1. Find the focal length of a convex mirror of radius of curvature 1m. 2. Focal length of a convex mirror is 50 cm. What is its radius of curvature? 3. Radius of curvature of a concave mirror is 25 cm. What is its focal length? 4. A concave mirror produces 10 cm long image of an object of height of 2cm. What is the magnification produced? 5. An object 1 cm high is held near a concave mirror of magnification 10. How tall will be the image? 6. An object 4 cm in size is placed at a distance of 25 cm from a concave mirror of focal length 15 cm. Find the position, nature and height of the image. 7. A converging mirror forms a real image of height 4 cm, of an object of height 1 cm placed 20 cm away from the mirror. Calculate the image distance. What is the focal length of the mirror? 8. A 4.5 cm needle is placed 12 cm away from a convex mirror of focal length 15 cm. Give the location of the image and the magnification. Describe what happens as the needle is moved farther from the mirror. 1. Find the focal length of a convex mirror of radius of curvature 1m. 2. Focal length of a convex mirror is 50 cm.
