WebApr 7, 2024 · Explanation: Object size is ho = 10mm and image size is hi = − 5mm since the image formed in front of a concave mirror is real and inverted. We are given that the image is formed 30 cm in front of the mirror. So, v = − 30cm. Now, we have the relation hi ho = − v u. Substituting the known values, we get, ⇒ − 5mm 10mm = − − 30cm u ⇒ u = − 60cm WebDocument Description: Detailed Chapter Notes - Ray Optics, Class 10, Science for Class 10 2024 is part of Class 10 preparation.
