A concave mirror forms real image of a point source lying on the optical axis at a distance of 50cm from the mirror. The focal length of the mirror is 25cm. The mirror is cut in two, and its halves are drawn at a distance of 1 cm apart in a direction perpendicular to the optical axis. Q. Two statements are provided. Choose which is true and which is false. Statement I: Image formed by half cut mirror has just half the intensity as that of the intensity of image formed by complete mirror. Statement II: More the lateral separation between the two halves of the mirror, less will be the separation between the two images, as show in the given situation.

Statement I: Keeping a point object fixed, if a plane mirror is moved, the image will also move. Statement II: In case of a plane mirror, distance of object and its image is equal from any point on the mirror
