(g) The set-up was created so that objects at
infinity would be focused on the screen at a
distance D=D=15.0 cm from the convex lens. The image you
considered in the previous step will be focused at a point that is
close but not exactly at the position of the screen. Calculate the
distance D′D′ from the convex lens where the image will
appear.
Answer all part please, ill leave good review
(7%) Problem 13: A convex lens is placed a distance D=15.0 cm in front of a projection screen for the purpose of imaging objects that are a great distance away, but the images appear at an image distance which falls short of the screen. -D -1 di Due to the supporting structures holding the lens and the screen, they may not be easily relocated. A student is assigned the task of placing a concave lens with a focal length Fp = -7.2 cm between the first lens and the screen to correct the problem.
