CBSE Important Questions for class X Science Chapter 10 Light-Reflection and Refraction it includes important questions from NCERT solution text book prescribes for class 10 Science. A convex lens has a focal length of 10 cm. At what distance from the lens should the object be placed so that it forms a real and inverted image 20 cm. away from the lens? What would be the size of the image formed if the object is 2 cm high? With the help of a ray diagram show the formation of the image by the lens in this case?
