The spectrum
is divided into seven types of radiation across the top of the diagram
from left to right: gamma rays, x-rays, ultraviolet (UV), visible, infrared,
microwave, and radio waves.
The diagram
indicates that wavelengths increase from short to long as you move across
the spectrum from left to right, starting with gamma rays and x-rays (short)
and ending with radio waves (long).
UV rays have
slightly longer wavelengths than gamma and x-rays. UV rays include UVC,
UVB, and UVA rays, which increase in wavelength respectively, from UVC
to UVA rays.
Visible rays
have longer wavelengths than UV rays.
