A Thin Lens Projects an Image of a Man as Shown

question 154

Short Answer

A thin lens projects an image of a man as shown in the figure. Rays marked A, B, and C travel to the lens from the man's ear. Draw the paths of these three rays after they have passed through the lens. Note that $\mathrm { A }$ is parallel to the principal axis, B goes through the center of the lens, C goes through the focal point on the left, and the point marked $f$ is the focal point on the right of the lens.
