What are EM Waves?
Electromagnetic
waves are formed when an electric field couples with
a magnetic field. Magnetic and electric fields of an
electromagnetic wave are perpendicular to each other
and to the direction of the wave....

Ultraviolet Waves
Scientists have divided the ultraviolet part of the
spectrum into three regions: the near ultraviolet, the
far ultraviolet, and the extreme ultraviolet. The three
regions are distinguished by how energetic the
ultraviolet radiation is, and by the "wavelength" of the
ultraviolet light, which is related to energy....
Infrared Waves
Infrared
light lies between the visible and microwave
portions of the electromagnetic spectrum. Infrared
light has a range of wavelengths, just like visible
light has wavelengths that range from red light to
violet. "Near infrared" light is closest in
wavelength to visible light and "far infrared" is
closer to the microwave region of the
electromagnetic spectrum....
X Rays
As
the wavelengths of light decrease, they increase in
energy. X-rays have smaller wavelengths and
therefore higher energy than ultraviolet waves. We
usually talk about X-rays in terms of their energy
rather than wavelength. This is partially because
X-rays have very small wavelengths. It is also
because X-ray light tends to act more like a
particle than a wave....
