But sometimes they hit a stone, sir, and bounce back a terrible distance!

More marbles would hit against the wood and bounce back than ever went through the little holes.

Air waves do the same thing; when they strike against a flat surface, they bounce back like a rubber ball.

You'd just hit the earth and then bounce back again, but there's no use of talking about that, because it never happened but once.

As soon as they strike the object you are looking at, they reflect (bounce back) from it to your eyes.
