Border Sign: Boundary of Waves and Ripples

A Spell Card of Yukari Yakumo from the world delirious with eternal summer (a Touhou LW original). In this attack, waves become ripples, then become waves once more. If this world's history was the same as our world's, this attack would probably be called ''Border Sign: Boundary of Wave and Particle.''
How much of a calm sea is calm with ripples, and how much is choppy with waves? Or is the sea calm and choppy simultaneously...? This is confusing.
