This question makes no sense. What wave power are you talking about? Is your refrigerator on a raft on the ocean with paddles driven by the waves?
EDIT: Sorry if I was a bit rough on you. Looking at your profile, I see that physics ain’t exactly your thing. Here’s a link that explains how a refrigerator works. I hope it’s not too far over your pretty little head.
