Question

Consider a marble (dot) and one eye (circle) in a room with two vertical mirror walls shown here “from above” as solid lines. Angle between mirrors is about 60^o.

a) Plot the likely location of the marble’s reflection in the left-most angled mirror in the figure, and using that trace the path of a light ray from marble to the angled mirror to the eyeball. Explain your method in words.

b) Plot the likely location of that first reflection’s image in the 2nd (bottom) mirror, and using that trace the path of a light ray from the marble to the eye which first bounces off the leftmost (angled) wall, and then reflects from the bottom mirror, before hitting the eye? As above, explain your process here.
