Assertion: Light from an object falls on a concave mirror forming a real image of the object. If both the object and mirror are immersed in water, there is no change in the position of the image. Reason: The formation of image by reflection does not depend on surrounding medium, so there is no change in position of image, provided it is also formed in water. (A) A (B) B (C) C (D) D | Numerade
