There is no definite end to earths atmosphere, but technically the border between the outer space and earth gets thinner as you move up from the earths surface.

ExplanationWhen you shake a rope, the particles in the rope move up and down, and the wave moves forward or away from the source of energy. The rope moves in a direction that is perpendicular
Nodes are the places where the rope doesn't move at all; antinodes occur where the motion is greatest.
Step 1
let's check the graph:
a) Nodes
and Antinodes
so, in the ripe there are 8 antinodes
therefore, the answer is
c) 8
