Water is transparent or not? I think - Pure water is transparent to the visible wavelengths of light, with maximum transmission of light in the blue portion of the visible spectrum. Pure water is almost totally transparent to such low frequency radiation. The maximum absorption varies to higher frequencies at higher temperatures when the weaker hydrogen bonding allows a quicker response to changes in the field [136]. Microwave ovens typically use radiation at 2.450 GHz (? 12.24 cm).
