A 6.00kg ball with a velocity of 9.00m/s along the positive x-axis collides with another ball of mass 0.800kg that is initially at rest. The collision last 0.250s. After collision, the 0.800kg ball has a velocity of 15.0m/s at 65.0°.

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.
