A lighthouse has 2 beacons that rotate together - but, not necessarily facing opposite directions. It can be a shorter time between the first and second flashes than between the second flash and the third flash (when the first beacon comes around for the second time). What is the ratio of the short time between flashes to the long time between flashes. If the beacons are set 120 degrees, apart along the rotation, what is the ratio?
