Heavy water and light water are both forms of water, but they differ in their composition and properties. Light water, also known as ordinary water, is the most common form of water found on Earth. It consists of two hydrogen atoms and one oxygen atom, with the hydrogen atoms being the light isotope, known as protium.
Heavy water lacks the characteristic blue color of light water; this is because the molecular vibration harmonics, which in light water cause weak absorption in the red part of the visible spectrum, are shifted into the infrared and thus heavy water does not absorb red light.
Water, for example, has the rare property of being lighter as a solid than as a liquid. If ice (solid water) were heavier than water, frozen water in a lake would sink to the bottom and pile up to the top, killing all the marine life. Water’s ability to store great amounts of heat helps living things survive through wide changes in temperature.
Heavy water is water composed of deuterium, the hydrogen isotope with a mass double that of ordinary hydrogen, and oxygen. Heavy water is used as a moderator of neutrons in nuclear power plants. It is also employed as an isotopic tracer in studies of chemical and biochemical processes.
3 Ιουλ 2023 · Heavy water, scientifically called deuterium oxide, is a variant of water wherein the regular hydrogen atoms are replaced by heavy hydrogen, commonly known as deuterium. Alternatively, it can be expressed as 2H 2 O or D 2 O.
Light water refers to water that contains normal hydrogen atoms (protium) instead of deuterium. It is commonly used as a control in experiments to contrast the effects observed with heavy water.

26 Ιουλ 2022 · Let’s start with light, because that’s where the plant gets the energy for photosynthesis. Here are some characteristics of light: Light travels in waves. The length of the wave is measured from one peak to the next and is called the wavelength, which differs for different colors of light. Visible spectrum. Philip Ronan. CC BY-SA 3.0
