Suppose you were asked to demonstrate electromagnetic induction. which of the following situations will result in an electric current?
a. a magnet is moving toward a wire loop.
b. a wire loop is moving away from a magnet.
c. a wire loop is rotated near a magnet.
d. all of the above

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.
