Formally I did not know what ripple means, but seeing examples in the movies where a stone makes the ripple after someone throws a stone to make steps on top of the water, then we have a ripple. It's a really cool sight to watch and fun too. I have tried it myself, making a ripple on water and it did not go as planned. For my persistence, I got close after trying it for a while, still trying to have fun.
