Then, sixty-seven years later, Isaac Newton published his Opticks, correctly stating that sunlight can be separated into several colors and thus raindrops simply separate the colors.
This is because the light rays have undergone one more reflection on the internal surfaces of the raindrops and are reversed in much the same way as left becomes right and right becomes left in a mirror.
So the same raindrop that is at an angle to reflect red light to you may be reflecting yellow or blue light toward another person standing a few feet to one side of you.
Boyer observes: “Within a raindrop the interaction of light energy with matter is so intimate that one is led directly to quantum mechanics and the theory of relativity. . . .
But as The Complete Illustrated Guide to Gambling puts it: “Determined gamblers will bet on which of two raindrops will first reach the bottom of a window pane, or on the number of hairs growing on a hirsute mole.”
