They used four identical nachlights and a dark plece of poster board. They labeled the lashights A, B. C. and D. Each Nashight had brand new bateries. The students ploced the flashlights at different distances from the poster boord. Then, the students umed on the flashlights and observed the circles of Ight that shone on the poster tboard. They ranked the crcles of Ight in order hrom most bright to least bright Distance from poster Brightness board (m) Flashlight rank 3.6 26 Which Ist is the best prediction of the order from most bright to lcast bright?
