Show WHY MILK REFLECTS light consisting of minute droplets of fat it throws back rays in every direction one Is often apt to forget that color is merely a reflection of light and that anything which reflects light perfectly will be the color of that light the roost most nearly perfect form to reflect Is a sphere the moon is bright because it reflects the sun the earth Is bright tor for the same reason as one can see atthe at the time of new moon when the part of 0 the moon hidden from the sun by the earth shines faintly from reflected earth light milk Is like a collection of moons it Is a liquid filled with minute droplets of fat each of them a perfect sphere when the light strikes these it Is reflected at every angle reflected on to other droplets of fat and by them reflected on and on until from every point in the milk the white light that strikes on the outside Is reflected ted think of marbles made of looking glass but so small that several thousand could be put on the head of a pin and you will see the reason for the reflection or the white color of milk when in the case of milk the number of these little reflecting drops grows smaller then the light is not reflected so much and the liquid grows more transparent absence of full reflection makes milk less white or in a sense more bluish as the of air makes blue sky and of water blue sea |
