Describe a method to measure the focal length of a concave mirror.

In an experiment to measure the focal length of a concave mirror. If was found that for an object distance of 0.30 m, the image distance come out to be 0.60 m. Let us determine the focal length.

Focal length of plane mirror is ......

A student performed the experiment of determination of focal length of a concave mirror by u-v method using an optical bench of length 1.5 meter. The focal length of the mirror used is 24 cm. The maximum error in the location of the image can be 0.2 cm. The 5 sets of (u,v) values recorded by the student (in cm) are: (42,56),(48,48),(60,40),(66,33),(78,39) . The data set (s) that cannot come from experiment and is (are) incorrectly recorded, is (are)

In an experiment to find focal length of a concave mirror a graph is drawn. The graph looks like ...........

A real image obtained by a concave mirror is 4 times bigger than the object. If the object is displaced by 3 cm away from the mirror, the image size becomes 3 times the object size. Find the focal length of the mirror.

Give definition of focal plane for concave mirror.

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