Electromagnetic waves are transverse waves that travel at the speed of light. The spectrum of their wavelengths results in waves that are used in many of our useful devices. The waves are formed by heat, electronics, and nuclear forces.

What are electromagnetic waves ? Light, microwaves, x-rays, and TV and radio transmissions are all kinds of electromagnetic waves. They are all the same kind of wavy disturbance that repeats itself over a distance called the wavelength.

Radiation is energy that travels and spreads out as it goes-- visible light that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves, infrared and ultraviolet light, X-rays and gamma-rays.

More about the Electromagnetic Spectrum Low energy photons (such as radio) behave more like waves, while higher energy photons (such as X-rays) behave more like particles. This is an important difference for scientists to know when they One is a special technique used in radio astronomy called "interferometry".

Understand that there are eight main types of electromagnetic waves, classified on the electromagnetic spectrum according to their wavelengths. Understand how each of the types of electromagnetic radiation is used or found in our everyday lives.
