In a longitudinal wave: The is the part of the wave where the particles of the medium are closer together.
The is the part of the wave where the particles of the medium are farther apart
The is the distance between compression or the distances between rarefactions.
The relates how close together the particles in the medium are at the compressions of the wave.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

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.

not copied too! hope this !
