The electromagnetic spectrum

The electromagnetic spectrum

1. The visible spectrum

   • using a prism, you can split up white light to form a spectrum.
   • part of a continuous spectrum of electromagnetic radiation
   • Red light has the longest wavelength.
   • Yellow light has a medium length wavelength

2. All the different types of electromagnetic waves travel at the same speed through space.

3. The light waves are refracted as they enter and leave the prism

4. The shorter the wavelength of the light, the more it is refracted

   • violet light is refracted the most
     • Violet light has the shortest wavelength.
   • red light is refracted the least
     • Red light has the longest wavelength.

5. ionising radiation

   • Radiation that can knock electrons out of atoms

6. Discoverys

   • Herschel discovered infrared light.
   • Ritter discovered ultraviolet light

7. Frequency of waves

   • Gamma rays have the highest frequency
   • Radio waves have the lowest frequency
   • X-rays
   • Utraviolet
   • Vsible light
   • infrared
   • Microwaves

8. Pentration

   • Alpha radiation is the least penetrating.
   • Beta is the second most penetrating
   • Gamma radiation is the most penetrating

9. UV Radiation

   • UV C radiation causes most damage to skin cells
   • UV A has the least effect on skin
   • UV B causes sunburn and can damage skin cells but not as much as UV C
