Reflection problem 3
Points A and B and two lines are given. Find the points
P and Q on the lines such that a ray of light from A reflected
in the two lines will pass through B.
|
Study the above construction. The ray must travel from A to P then
to Q and finally to B. Note that this construction does not work
for certain positions of the points and lines. See if you can make
this construction yourself:
