WebYes. There are three ways that heat can transfer, from a hotter body to a colder one—conduction via direct contact; convection via the flow of fluids; and radiation via the propagation of electromagnetic waves. An object … 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.
