K.C.S.E Physics Q & A - MODEL 1999PP2QN02
a) An object O placed in front of a converging lens Lo forms an image 1 on the other side of the lens. Another converging lens Lc placed such that the two lenses form a compound microscope.
i) Draw a reason of the set up and sketch the rays to show how the final image is formed.
ii) Give a reason why the focal length of Lo must be greater than that of Lc
b) An object is placed 30cm from a converging lens. A focused image is formed on a screen placed 30cm from the same lens on the other side. The screen in now moved 5cm towards the lens. Determine the distance the object must be moved so that a focused image is formed on the screen.
