It is not possible to change the frequency/wavelength or adjust the phase of the Sine Time output from the Time node. You can only remap values, such as using a Multiply to adjust the amplitude of the wave. If you need to control the frequency, use the Time output instead, Multiply by your frequency. To adjust phase use Add or Subtract. You would then put into a Sine node. Can also Multiply again after this to adjust amplitude, same as before.
