A screen is placed a distance d = 42.0 cm to the right of a small object. At what two distances to the right of the object can a converging lens of focal length +S,80 cm be placed if the real image of the object is at the location of the screen? sf s-f (Hint: Use the thin lens equation in the form s'= so s's - ) = sf. Write s'= d-s and solve for s in the resulting quadratic equation.) shorter distance 139 41 862 X cm longer distance X cm For this lens, what is the smallest value d can have and an image be formed on the screen? 232 cm Additional Materials Thin Lenses
