WebThese lines are called blackbody or Planck curves, and show that the blackbody emits radiation at all wavelengths. The area under the line is the total energy radiated per unit of time per unit of surface area by the object at that temperature. So, as can be seen above, the hotter the object the more energy, or power is radiated by the blackbody.
