Year 9 Electromagnetic Spectrum independent learning task
The visible spectrum is only a small part of a wide group of electromagnetic waves. In order
from smallest to largest wavelength, these are; gamma rays, X-rays, ultraviolet waves,
visible light, infra-red waves, microwaves and radio waves. These make up the
electromagnetic spectrum. Though we cannot see these other types of waves, they can be
detected and are used in a variety of applications.
