CBSE Class 12 Physics Reflection from Curved Surface Solved Examples. Please refer to the examination notes which you can use for preparing and revising for exams. These notes will help you to revise the concepts quickly and get good marks.
Ex.1 A girl stands at a distance 30 cm from the mirror. She is able to see her erect image but of 1/5 height of actual height. The mirror will be :
(A) plane mirror (B) concave mirror (C) convex mirror (D) plane convex mirror
Sol. Small and erect image is formed only by convex mirror. Plane mirror from images equal to object and concave mirror form images bigger than object.
Hence correct answer is (C).
Ex.2 An object is placed at a distance of 50 cm from a convex mirror. A plane mirror is placed in front of the convex mirror in such a way that it convers half of the convex mirror. If the distance between object and plane mirror is 30 cm then there is no parallax between the images formed by two mirrors , the radius of curvature of convex mirror will be :
(A) 50 cm (B) 25 cm (C) 12.5 cm (D) 100cm
Sol. The image will be formed by the plane mirror at a 30 cm behind it, while the image by convex mirror will be formed at 10 cm behind the convex mirror.
Since for convex mirror u = 50 cm as shown in figure. v = 10 cm
r = 2 f = 25 cm
Hence correct answer is (B).
Ex.3 There is a convex mirror of radius 50 cm. The image of a point at a distance 50cm from the pole of mirror on its axis will be formed at :
Ex.4 A particle is moving at a constant speed v from a large distance towards a concave mirror of radius R along its principle axis. Find the speed of the image formed by the mirror as a function of the distance x of the particles from the mirror.
