At what speed does heat radiation travel? What path does it …

WebElimination of the effects of convection can be effected as follows: (a) by limiting the aper- ture through a tube arrangement, e.g., to 5°-10°; (b) by providing an envelope transparent to the atmospheric radiation and at effectively the same temperature as the receiver; (c) by providing an artificial heat loss so great as to swamp the effect ... WebAnswer: For heat to be transferred by radiation no medium is required; only an emitting surface and a receiving surface are required. The heat emitted is proportional to the surface absolute temperature to the power 4 and heat received also proportional to its absolute temperature to the power.

WebRadiation differs from Conduction and Convection heat t transfer mechanisms, in the sense that it does not require the presence of a material medium to occur. Energy transfer by radiation occurs at the speed of light and suffers no attenuation in vacuum. Radiation can occur between two bodies separated by a medium colder than both bodies. http://www.mhtl.uwaterloo.ca/courses/ece309_mechatronics/lectures/pdffiles/summary_ch12.pdf
