A short straight object of height 100 cm lies before the central axis of a spherical mirror, whose focal length has absolute value . The image of object produced by the mirror is of height 25 cm and has the same orientation of the object. One may conclude from the information.
View answer and explanation
Correct option: D
Image is virtual, opposite side of convex mirror
Option D (Image is virtual, opposite side of convex mirror) is correct because a convex mirror always produces virtual, erect, and diminished images.

An object 5 cm tall is placed from a concave spherical mirror which has a radius of curvature of . The size of the image is
Red colour is used for danger signals because
A ray of light is incident on the hypotenuse of a right-angled prism after travelling parallel to the base inside the prism. If is the refractive index of the material of the prism, the maximum value of the base angle for which light is totally reflected from the hypotenuse is
Statement-A: The minimum distance between an object and its real image formed by a convex lens is .
Statement-B: The distance between an object and its real image is minimum when its magnification is -1. Assertion: We cannot produce a real image by plane or convex mirrors under any circumstances.
Reason: The focal length of a convex mirror is always taken negative. If both the object and image are at infinite distance from a refracting telescope its magnifying power will be equal to
