Why does the sound of something moving away from you seem to change to a lower and lower pitch? a) as the source moves away, the increased distance creates more interference; so the pitch drops. b) as the source moves away, the frequency of the sound waves is being compressed, so the pitch drops. c) as the source moves away, the sound waves speed up to reach the observer; this causes the pitch to drop. d) as the source moves away, the sound waves stretches out relative to the person standing still; so the pitch drops.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
