Question

how go you find the focal length of a lens experimentally by u-v method?​

Answer 1

Answer:

In order to find the focal length of a lens experimentally we have to use the UV method. The formula for focal length is the ratio of product of UV to sum of UV. Where U is the object distance and V is the image distance.

Answer 2

• The formula for focal length is the ratio of product of UV to sum of UV. Where U is the object distance and V is the image distance. Take a candle and place it 60cm away from a convex lens such that it lies along the principal axis
