Summary
[edit]DescriptionHole in Cavity as Blackbody.png | The image depicts the practical implementation of a black body by a small hole entrance to a large cavity with blackened walls. Any light ray entering through the hole is almost entirely absorbed, hence the hole appears as a true black surface. Since the hole is very small, the interior of the cavity contains radiation almost in thermal equilibrium with the walls maintained at a fixed temperature. Hence the hole emits nearly true blackbody radiation. |
