## Class 10 Physics Chapter 12 Important Numericals Problems

• An object 10.0 cm in front of a convex mirror forms an image 5.0 cm behind the mirror. What is the focal length of the mirror?
• An object 30 cm tall is located 10.5 cm from a concave mirror with a focal length of 16 cm. (a) Where is the image located? (b) How high is it?
• An object and its image in a concave mirror are of the same height, yet inverted when the object is 20 cm from the mirror. What is the focal length of the mirror?
• Find the focal length of a mirror that forms an image 5.66 cm behind the mirror of an object placed at 34.4 cm in front of the mirror. Is the mirror concave or convex?
• An image of a statue appears to be 11.5 cm behind a concave mirror with a focal length of 13.5 cm. Find the distance from the statue to the mirror.
• An object 4 cm high is placed at a distance of 12 cm from a convex lens of focal length 8 cm. Calculate the position and size of the image. Also, state the nature of the image.
• A convex lens of focal length 6 cm is to be used to form a virtual image three times the size of the object. Where must the lens be placed?
• The power of a convex lens is 5 D. At what distance the object should be placed from the lens so that it is real and a 2 times larger image is formed?
