FUNDAMENTALS OF THERMAL RADIATIONThermal radiation heat transfer between surfaces

Radiation differs from the other two heat transfer mechanisms i n that it does not require the presence of a material medium to take place In fact energy transfer by radiation is fastest at the speed of light and it suffers no attenua tion in a vacuum Also radiation transfer occurs Thermal radiation heat transfer is one of fundamental modes of heat transfer All matter at a nonzero absolute temperature emit electromagnetic waves which are called thermal radiation Thus the heat transfer by thermal radiation is everywhere around us Human body is much more sensitive to
