 A basic wave function for a travelling monochromatic wave can be written as:

 Schrodinger assumed that a matter wave should have the same wave form. From this, we can derive $k =
 \frac{2*\pi}{\lambda} = \frac{2 * \pi * p}{h} $, using the de-Broglie-wavelength as mentioned above. With $ v = f *
 \lambda $ for each wave, one can also conclude that $\omega = 2 * \pi * f = 2 * \pi * \frac{v}{\lambda} = \frac{2 * \pi
