In fission reactions, how must the binding energy per nucleon vary? a. the binding energy per nucleon remains constant as atomic number increases. b. the binding energy per nucleon increases as atomic number increases. c. the binding energy per nucleon decreases as atomic number increases. d. none of the above

what is the actual question though?

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.
