In radiative heat transfer, heat is transferred between bodies by electromagnetic radiation. In natural radiative heat transfer (that which happens when the electromagnetic radiation is generated naturally by heat), the spectrum of this radiation is that of a

Heat transfer — is a discipline of thermal engineering that concerns the exchange of thermal energy from one physical system to another. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and phase change … Wikipedia
Radiosity (heat transfer) — In the fields of optics and heat transfer, radiosity is the total emitted and reflected radiation leaving a surface. The diffuse radiosity (J) is the integral of the hemispherical spectral radiosity (J {lambda}) over the spectrum::J = int… … Wikipedia
Radiative forcing — In climate science, radiative forcing is generally defined as the change in net irradiance between different layers of the atmosphere. Typically, radiative forcing is quantified at the tropopause in units of watts per square meter. A positive… … Wikipedia
Wireless energy transfer — or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous,… … Wikipedia
Form factor (radiative transfer) — In physics, form factor (usually written e ) of a material, sometimes called emissivity, relates the proportion of energy transmitted by that object which can be transferred to another object.For instance, an object with surface area A transmits… … Wikipedia

Apollo Moon Landing hoax conspiracy theories — are claims that some or all elements of the Apollo Moon landings were faked by NASA and possibly members of other involved organizations. Some groups and individuals have advanced various theories which tend, to varying degrees, to include the… … Wikipedia
