This is a Sea Waves icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,300 icons, all in the same style and quality.
The icon for sea waves is three lines that are drawn to represent the up and down motion that waves make when the ocean water is moving. The three likes are placed one under the other, because that way it looks like a body of water.
