Radiation and temperature

  1. Jun 16, 2006 #1
    As I was doing my revision I came across this question though only 2 marks but I haven't got any ideas on it.

    The radiation emitted by a hot boday may be used as a means of determining the temperature of the body. Suggest and explain a property of the radiation that could be used for this purpose. Name one advantage and disadvantage of this method for measuring the temp.

    From my understanding of radiation, they are photons since they emit electromagnetic radiation at all temperatures. But how do I use this property to measure the temperature of a certain body? I can't relate this quanta of energies to temperature?

    Any help is appreciated!
