When water wave flows from shallow water into deep water, how do the frequency, wavelength and speed change?

Pls include explanation. Thanks.

The frequency of the same wave is always the same.
However, the speed of wave travel in different material is different.

The refraction index of light in a material is defined as speed of light $c$ divide by light speed in that material $v$, i.e. $n=\frac{c}{v}$

Are you talking about wave move on the water surface or wave traveling under the water surface (in the depth water)?
