Just reverse Easy Ray #1 and you'll have Easy Ray #2.
Incident light leaving the object towards f will reflect parallel to the OA.
Draw Easy Ray #2 on the same diagram as Easy Ray #1.
Notice where the two reflected rays intersect. Since the reflected rays are what you actually see,
this point of intersection represents where you should observe the image of the tip of the arrow.
We'll come back to the image later, but first...
Why might Easy Ray #3 be called the "normal" ray?
