how to make a wave effect?

Can you please help, the texture itself needs to take the shape of a wave.
I tried to do it through Polar Coordinates, but it turns out to be some kind of mess

Can you give more context as to the shape of the wave, how it’s being displayed/animated, and the type of environment you’re making it for? Is it wrapping to a round island or is it a particle based card fired along a longer coastline? Any screenshots of the scenario?
