Answer 2

• A perfect reflector is a name given to this item.
• Radiation: Radiation is a means of transferring heat from point A to point B that does not need the use of a medium. Radiation, for example, is how the Sun's heat reaches the Earth. Emission, Absorption, and Reflection Some heat radiation is reflected, some is absorbed, and the remainder is released when it strikes a surface.
• If the absorptive power is a the transmission power is t, and the reflecting power is r, then: 1 = a + r + t The item works as a perfect reflector for a=t=0 and r=1.
• The item operates as a perfect black body when t=r=0 and a=1.
