Focal length of a concave mirror is

Explain an experiment to determine the focal length of a concave mirror by u-v method.

Four students A, B, C and D performed the experiment to determine the focal length of a concave mirror by obtaining the image of a distant tree on a screen. They measured the distances between the screen and the mirror as shown in the diagrams given below : The correct value for focal length will be obtained by the student :

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)
