11- The focal length of a C
lens is 10cm.
a) Draw a diagram (scale 1/
ngth of a converging
a diagram (scale 1/2) showing the
al center O and the foci F and F of
Two
rays
falling on
b) Given:
the lens.
the
converging lens come out of a very far
point A on the optical axis so that these
rays are parallel to each other and
parallel to the optical axis. Construct the
path of these rays through the lens and
deduce the position of the image A of A'
given by the lens.
