    Microwaves
  • How do microwave ovens work
    Microwaves are absorbed by the water molecules in the food or object being heated
    This transfers energy to them
  • Can the microwaves used in satellite communication be absorbed by water molecules?
    No because if they were absorbed by water molecules they wouldn’t be able to pass through the atmosphere
  • What is infrared radiation emitted from
    Emitted from all object that have thermal energy
  • 3 uses of infrared radiation
    In infrared cameras to detect motion or monitor temperature
    To heat food in a toaster or grill
    To heat a room via an electric radiator
