What Is Radiofrequency Energy (Rf)?

Radiofrequency (RF) energy is another name for radio waves. It is one form of electromagnetic energy that makes up the electromagnetic spectrum. Some of the other forms of energy in the ... Continue reading

Bizarre Boiling

The next time you're watching a pot of water boil, perhaps for coffee or a cup of soup, pause for a moment and consider: what would this look like in space? Would the turbulent bubbles rise or fall? ... Continue reading

Without buoyancy, the vapor produced by boiling simply floats as a bubble inside the liquid after the heating has stopped. Surface tension effects cause the many small bubbles produced to coalesce into one large sphere.

Ultraviolet Light

Ultraviolet light is a form of radiation which is not visible to the human eye. It's in an invisible part of the 'electromagnetic spectrum'. Radiated energy, or radiation, is given off by many ... Continue reading

Our Sun emits light at all the different wavelengths in the electromagnetic spectrum, but it is ultraviolet waves that are responsible for causing our sunburns. This is an image of the Sun taken at an Extreme Ultraviolet wavelength.

Nuclides & Isotopes

An atom that has an unbalanced ratio of neutrons to protons in the nucleus seeks to become more stable. The unbalanced or unstable atom tries to become more stable by changing the number of neutrons ... Continue reading
