Astronomy — The Wavelengths of Light

A prism bends light by an angle that depends on the wavelength of the light. Short wavelengths bend the most and long wavelengths bend the least. Thus, white light passing through a prism is spread into a spectrum.

    Type of wave                Wavelength in nanometers

Gamma rays                      10^-5 to 10^-1

X rays                          10^-1 to 10¹

Ultraviolet rays                10¹  to 10²
