1. Radiation is the transfer of energy as electromagnetic waves.
2. Electromagnetic waves are measured by frequency or wavelength. Electromagnetic spectrum is a range of frequencies or wavelengths that an
electromagnetic wave can have.
3. There are two parts of the spectrum: Visible and invisible Gamma rays, X-ray, Ultraviolet, Infrared, microwaves, and radio waves are invisible radiations.
Sunlight is the visible spectrum
4. The shorter the wavelength, the higher the frequency and the energy.
5. Gamma, X-rays and Ultraviolet are very energetic while Infrared, microwaves, and radio waves are less energetic.
