Q. A screen is placed 90 cm from an object. The image of the object on the screen is formed by a convex lens at two different locations separated by 20cm. Determine the focal length of the lens.
Answer
Distance among the image (screen) and the object, D=90cm
Distance between two location s of the convex lens, d=20cm
Focal length of the lens=f
Focal length is related to d and D as:
Therefore the focal length of the convex lens is 21.39 cm
