Physics Facts

Sonic Boom

They sound like thunder, but they're not. They're sonic booms, concentrated blasts of sound waves created as vehicles travel faster than the speed of sound. To understand how the booms are created, ... Continue reading

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.

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.

Does Earth Have Its Own Neon Sign?

You might wonder what the Northern Lights and neon signs have in common. Actually, a lot! What makes luminous colors shimmer across the Northern sky? The answer is in the Sun. Charged particles ... Continue reading
