Wind does not affect which type of heat?

Radiant heat is not affected by wind because it involves the transfer of energy through electromagnetic waves, primarily infrared radiation. This means that radiant heat can travel through a vacuum or clear air without relying on a medium, such as wind, to move it.

In contrast, conduction heat is the transfer of heat through direct contact between materials, and it does not involve any movement of air. However, it can be influenced indirectly by wind if the wind cools the surface temperature or affects the heat exchange at that interface.

Convection heat, on the other hand, pertains to the movement of heat through fluids (liquids and gases) caused by the motion of the fluid itself. Wind directly impacts convection heat as it can facilitate the movement of air, enhancing heat transfer through this process.

Thus, while conduction and convection can be influenced by environmental factors including wind, radiant heat stands alone in its capacity to propagate independently of such influences.
