A convex mirror of radius of curvature 1.6m has an object placed at a distance of 1m from it. The image is formed at a distance of

A convex mirror has radius of curvature of 20 cm. An object is placed at such a distance from the mirror that the size of image is exactly half that of the object. The object must be at :-

A convex mirror forms a real image 5 times the size of the object placed at a distance of 20 cm from it. The radius of curvature of the mirror is

An object is placed at a distance of 40 cm in front of a convex mirror of radius of curvature 40 cm. List four characteristic of the image formed by 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:

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:

A convex lens of focal length 15 cm is placed in front of a convex mirror co-axially 5 cm from the mirror. The image of an object placed at a distance 20 cm from the lens found to have been formed over the object. Estimate the radius of curvature of the mirror.

A convex mirror has its radius of curvature 20 cm. Find the position of the image of an object placed at a distance of 12 cm from the mirror.
