A short straight object of height 100 cm lies before the central axis of a spherical mirror whose focal length has absolute value |f| = 40cm. 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:

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?

The focal length of a concave mirror is 30 cm.Find the position of the object in front of the mirror,so that the image is there times the size of the objects.

An object is placed at 15 cm in front of a concave mirror whose focal length is 10 cm. The image formed will be

An object is placed at 50 cm in front of a concave mirror of focal length 25 cm. What is the nature of the image produced by the mirror ?

The image formed by a convex mirror of focal length 30 cm . is a quarter of the object. What is the distance of the object from the mirror ?

The image formed by a convex mirror of focal length 30 cm is a quarter of the object. What is the distance of the object from the mirror?

The image formed by a convex mirror of focal length 20 cm is a quarter of the object. What is the distance of the object from the mirror?

An object of height 1cm is kept perpendicular to the principle axis of a convex mirror of radius of curvature 20cm . IF the distance of the object form the mirror is 20 cm then the distance (in cm ) between heads of the image and the object will be:
