The distance between the concave lens and the screen, LI2 is measured as v cm.
Using the values of u and v, the focal length of the concave lens is calculated using the formula, f= uv/u-v.
To repeat the experiment, remove the concave lens and bring the screen to the initial position.
Hope this will help u.. :-)
