An incident ray of light strikes a diamond at an angle of 45°. The index of refraction of air is 1.0003 and the index
of refraction of a diamond is 2.42.
What is the angle of refraction rounded to the nearest
whole number?
2°
17
19
45

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.
