A small surface of area A 1 = 3 cm 2 emits radiation as a blackbody at

Question:

A small surface of area A₁ = 3 cm² emits radiation as a blackbody at T₁ = 1000 K. A radiation detector (A₂) is placed normal to the direction of viewing from surface A₁ at a distance L, as shown in the figure. If the radiation detector is measuring an irradiation of 100 W/m², determine the distance between the radiation detector and surface A₁. F A = 3 cm T = 1000 K L Radiation detector A G = 100 W/m
