On the axis of a spherical mirror of focal length f a short linear object of length L lies on the axis at a distance mu from the mirror. Its image has an axial length L' equal to

An object of height h is held before a spherical mirror of focal length | f | = 40 cm . The image of the object produced by the mirror has same orientation as the object and has height = 0.2 h . Is the image real or virtual ? Is the image on the convex or concave? What is focal length of mirror with proper sign?

An object is placed in front of a spherical mirror of focal length f. If x and x' recpectively represent the distance of the object and the image from the focus, then

The distance of an object from a spherical mirror is equal to the focal length of the mirror. Then the image:

The distance of an object from a spherical mirror is equal to the focal length of the mirror. Then the image.
