Newton's Law of Cooling

Notice that initially the temperature of the hot liquid drops very fast meaning the rate of cooling is high, but as the temperature decreases, the rate of cooling decreases and takes infinite time to reach the surrounding temperature.

Planck's Law of Black-body Radiation: 
Wein's Displacement Law:

Useful to show two different temperatures and the wavelength where the maximum intensity occurs.

Temperature to Colour relationship

As temperature of source increases the colour of radiation changes to higher frequency. Wein's displacement law and Stefan's Law.
