And it's just that simple. The light that is scattered returns all wavelengths to your eyes thus making the water appear white.

Watrefalls have a lot of water flowing through a cross section very rapidly.Now consider of a plane surface perpendicular to the flow of water.
Through this area the water flows and the molecules are replaced very rapidly.Water refracts light of all colours and then it reflects back due to internall refclection and so a mixture of colours is produced which looks white.

when water falls so fast, it bounces and jumps over itself: this creates foam, which appears white
a waterfall has SO MUCH high-speed water that it appears completely white!

Water gets airreted (air gets between molecleales), that way it foams, and looks white.

Usually there are air bubbles mixed in the water or water is flowing in thin sheets and there is air behind them.

as cream on Milk is not always white. White colour represents...mixture of air...you may call it....flush...which is made with bubbles....
