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

Focal length of a concave mirror is

In the experiment to determine the focal length of a concave mirror by graphical methods the u - v graph 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)

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 :

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.

Arrange the following steps in a sequential order to determine the focal length of a concave mirror by distant object method. (A) Place a white screen in front of the mirror and adjust the position of the screen until a sharp images is formed. (B) Focus the mirror towards a distant object. (C) Mount the concave mirror on a mirror stand. (D) Measure the distance between the screen and the mirror. This gives the focal length.

In an optical bench experiment to measure the focal length of a concave mirror random error in focal length will be

Describe an experiment to find the focal length of a concave mirror and to find the nature of the image when the object is at finite distance.

In order to determine the focal length of a concave mirror by obtaining the image of distant object on screen, the position of screen should be
