Blackbody Radiation

  1. Jun 28, 2015 #1
    The black body curve of intensity vs frequency increases, reaches a maximum value and then decreases. As the temperature increases, the peak of the curve shifts to lower wavelengths or higher frequencies.
    1) I only vaguely understand the relation between the nature of this graph and the fact that energy is in discreet packets. Can someone give me a simple explanation?
    2) As the peak keeps moving to lower frequencies with increase in temperature, will the object eventually become invisible as we reach really high temperatures and it gets to the UV region?
