Question

Readings of the experiment to find the value of v for different values of u in case of a concave mirror and to find its focal length

Answer 1

The results will be as follows :

f that is calculated by the given formula of f = u x v / u + v will be 15.05 cm.

f calculated from u - v graph will be 15.14 cm.

f calculated from 1 / u and 1 / v graph will be 15.12 cm.

And other calculations are given in the following images.

Answer 2

Answer:

f is -13. 2cm

hope it will help u
