Synthetic Material Facts

Synthetic materials are materials created by humans, such as plastics. Many synthetic materials are polymers.

Electromagnetic Wave Facts

The electromagnetic spectrum is the complete range of radiation sent out by electrons. It is given off in tiny packages of energy called photons, which can be either particles or waves. Electromagnetic waves vary in length and frequency. The shorter the wave, the higher its frequency (and also its energy). The longest waves are over…

Facts About Air Pressure

Although air is light, there is so much of it that air can exert huge pressure at ground level. Air pressure is the constant bombardment of billions of air molecules as they zoom about. Air pushes in all directions at ground level with a force of over 1 kg per sq cm – that is…

X-ray Facts

X-rays are a form of electromagnetic radiation, as are radio waves, microwaves, visible light and ultraviolet. They all travel as waves, but have different wavelengths. X-ray waves are much shorter and more energetic than visible light waves. X-rays are invisible because their waves are too short for our eyes to see. X-rays are made when…
