Electromagnetic fields (EMFs) can penetrate water to varying degrees depending on the frequency of the EM radiation. Different frequencies behave differently when interacting with water. Here's an overview of the general behavior of EM radiation across the spectrum when passing through water:
Radio waves and microwaves: These lower frequency EM waves can penetrate water relatively easily. They interact with water molecules, causing them to vibrate and generate heat. This is the principle behind microwave ovens, where microwaves are absorbed by water molecules, heating up the food.
Infrared (IR) radiation: Infrared radiation, which includes heat radiation, is also absorbed by water. The absorption depends on the specific frequency within the IR range. Some frequencies are absorbed more strongly than others, leading to heating of the water.
Visible light: Visible light is also absorbed by water, although the degree of absorption depends on the color or wavelength of the light. For example, red light is absorbed less than blue light in water.
Ultraviolet (UV) radiation: UV radiation is partially absorbed by water. The degree of absorption depends on the specific wavelength of the UV light. Shorter UV wavelengths (UVC) are absorbed more strongly than longer UV wavelengths (UVA and UVB).
X-rays and gamma rays: These high-energy EM waves have a higher ability to penetrate matter. Water can attenuate (weaken) X-rays and gamma rays, but they can still penetrate water to some extent, depending on the energy of the radiation.
It's worth noting that the behavior of EM radiation passing through water is complex, and factors like the intensity of the radiation, the thickness and quality of the water, and the specific characteristics of the EM source can affect the results. Additionally, when considering the "whole spectrum" of EM radiation, it includes a vast range of frequencies, each with its own specific interaction with water.
To provide specific results for each frequency of the spectrum and their interaction with water, detailed measurements and calculations would be required, taking into account the specific source, the power and intensity of the EM radiation, and the characteristics of the water medium. Such an analysis goes beyond the scope of a general response and would require specific expertise and equipment.
