WebNov 14, 2012 · There are lots of ways to do this, one such way is. x (t) = (2+.5*cos (nt))cos (t) y (t) = (2+.5*cos (nt))sin (t) where 0\leq t\leq 2\pi and n\in \ {3, 4, 5, ....\} If you vary the .5 it will vary the sharpness of the … WebPhase Speed. In reality, waves don't have an arbitrary phase speed. It is related to the wave number, c = √ g k = √ gλ 2π c = g k = g λ 2 π, where g g is the pull of gravity, roughly 9.8 on Earth. This is true for waves in deep water. In shallow water the water depth also plays a role, but we won't cover that here.
