A film of soapy water (n = 1.33) on top of a plastic cutting board (n > 1.33) has a thickness of 243 nm. What color is most strongly reflected if it is illuminated perpendicular to its surface? violet (380 nm ≤ λ < 450 nm) blue (450 nm ≤ λ < 495 nm) green (495 nm ≤ λ < 570 nm) yellow (570 nm ≤ λ < 590 nm) orange (590 nm ≤ λ < 625 nm) red (625 nm ≤ λ ≤ 750 nm)

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
