In order to measure focal length of a diverging
lens (L2), we set up the following experiment (as shown in
the right figure). It uses another converging lens (L1). An
object (o) is placed in front of lens (L1). The image of the
object can be seen on a screen (S,), which is located 20cm
behind lens (L2). Next, after removing lens (L2) only, the
image can be restored (seen) by moving screen 5cm toward
lens (L1) to a new location of S2. Please compute the focal
length of lens (L2).

The Block shown is 40cm thick.
(d) The block is shown below. A 25° line is displayed by a diagonal dashed line. The incident light is directed at the
block along the 25° line. The light enters the front surface and exits the second side back into air some time later.
i. Print or redraw the diagram below, sketch the light path as the ray enters and passes through to the air on the backside
of the block. Please use a ruler or make relatively straight lines.
ii.
When the light exits the block back into the air, will the ray travel parallel to the 25° line or at an angle to it?
Determine the angle between the exiting ray and the 25° line or the distance between the two lines if they are
parallel.
