Does aluminum foil refract light? why?

yes it does it because the material cause it to refract and the stronger it is the more it will refract

where is the circuit diagram ?

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.
