The body radiates energy via thermal conduction via the skin to the air, clothes, and so on around the body. The small amount of energy would as well be radiated as electromagnetic radiation with the peak wavelength directly associated to the Kelvin temperature of skin.
Fermat's principle: principle of least time (P. de Fermat): The principle, put onward by P. de Fermat that explains the path taken by a ray of light among any two points in a system is for all time the path which takes the least time.

The molecules of many dielectrics possess an electric dipole moment without having an external electric field. In such molecules centres of their positive and negative charges are displaced with respect to each other and therefore form a dipole. Such materials are kno
