Progressive waves — practice question

A wave’s speed in deep water is determined by its wavelength $L$ and the acceleration of free fall $g$. Which equation could represent the speed $v$ of the wave?

  • A$v = \sqrt{\frac{gL}{2\pi}}$
  • B$v = \frac{gL}{4\pi^2}$
  • C$v = 2\pi\sqrt{\frac{g}{L}}$
  • D$v = \frac{2\pi g}{L}$
