Light from very far away source falls on the lens. The distance of final image from the mirror is Medium A. 22.5 cm B. 7.5 cm Next. WebMar 25, 2024 · Problem 10: If the object distance is 32 cm in front of the concave mirror, the focal length of the mirror is 16 cm. State the nature and the size of the image formed. Solution: Given that, Object distance, u = -32 cm. Focal length , f = -16 cm. For image distance use mirror formula, 1 / v + 1 / u = 1 / f. Therefore, 1/ v + 1/ -32 = 1/ -16. or
