Ray Bender observes that light striking a sheet of material at a 30 degree angle to the surface, is bent to an angle of 36 degrees relative to the normal as it passes through the material. Through what material is the light passing?
A)
Ruby
B)
Water
C)
Pyrex
D)
Crown glass

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.
