Consider a black body emitting 0.2 W/m^2 of thermal radiation between zero and 0.01 ?m wavelengths and 1.2 W/m^2 above 0.01 ?m. What is the total radiation emitted per unit area? What is emitted at exactly 0.01 ?m?
What will be an ideal response?
The total radiation is the sum, or 1.4 W/m^2. The amount of radiation emitted at exactly 0.01 ?m is, in the limit, zero.
