Summary[edit]
| Description |
English: 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.Ελληνικά: Το φως που εισέρχεται στην κοιλότητα από μια μικρή οπή, έπειτα από πολλαπλές αντανακλάσεις απορροφάται σχεδόν ολοκληρωτικά από τα τοιχώματα |
