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
WebOptics is the popular branch of physics which deals with the determination of behaviour and the properties of the light. It also considers the interactions with the matter and also with the instruments which we need to detect it.
