  • Radiation
    • Radiation is a method of heat transfer
    • Thermal Radiation is the transfer of electromagnetic waves
      • They transfer waves due to electric/magnetic field vibrations
    • Infrared Radiation
      • It can travel through empty space or vacuum.
      • Travels at speed of light - 300,000,000 m/s
    • Greater difference in temperature - greater flow of energy
    • Hot objects EMIT IR radiation Colder objects ABSORD IR Radiation
    • If a temp of object remains constant then they are absorbing and emitting heat at same rate.
