What does the law of conservation of energy state about energy in a closed system

Explanation:

Law of conservation of energy: The energy of the system can neither be created nor destroyed. It can be transformed from one form to another.

In a closed system, the energy remains conserved. It is isolated from the surrounding.

For example, the ball is rolling from the inclined plane. At the top of the inclined plane, the potential energy is maximum. When the ball starts rolling then the kinetic energy starts increases. Here, the potential energy is converted into kinetic energy. The energy transformation takes place.

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.
