are all related and have different length of wave. (a.k.a. wavelength). All 
objects emit a certain amount of black body radiation because of 
their temperatures and in accordance with it. Generally speaking, the 
temperature has straight effect on its infrared radiation it means that the 
infrared radiation increases by rising temperatures.

Emissivity

The 

 of a material (usually written  or  ) is the relative ability of 

emissivity

e

its surface to emit energy by radiation. It is the ratio of energy radiated by 
a particular material to energy radiated by a black body at the same 
temperature. A true black body would have an  = 1 while any real object 
would have  < 1. Since it is the ratio of tow numbers with similar 
dimension, therefore it is a dimensionless quantity.

See emissivity information for actual temperatures. Reflective 
objects result in lower than actual temperature measurements. 
These objects pose a burn hazard.
