He then measures how many units of light are being reflected off each piece of paper. He finds that each paper is reflecting exactly 30 units of light (top panel in image below). If he then moves the pieces of paper into the sunlight, where they are all lit by EXACTLY the same amount of light (bottom panel below). When he measures how much light they are reflecting, which of the following is the most likely order, from MOST light reflected to LEAST light reflected?
