Wavelengths is a common way of describing light waves. ... The speed of light is the velocity of electromagnetic wave in vacuum, which is 300,000 km/sec. Light travels slower in other media, and different wavelengths travel at different speeds in the same media. When light passes from one media to another,

Different wavelengths of light cause different colors and can result in "invisible shades" of electromagnetic radiation such as ultraviolet and infrared radiation. The following pictures compare animations of the classical view of light for four different wavelengths (225 and 300 nm are ultraviolet radiation;

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 ... In radio astronomy, astronomers tend to use wavelengths or frequencies.

To describe the differences between types of light like visible and x-ray, scientists often talk about the length of the light's waves or "wavelength." The various types of light that make up the electromagnetic spectrum differ in the length of their waves.
