Are you familiar with daylight tanks for film processing? They work as advertised using right angles.

Are you familiar with daylight tanks for film processing? They work as advertised using right angles.
- pdkl95 5y agoThe last time I used a daylight tank was in the mid '90s so maybe newer models are different, but I believe they are made out of black/dark plastic? Several right angle turns of black plastic provides multiple opportunities for a visible-light photon to be absorbed into a black body where it should be re-radiated as infrared (heat). A hole/leak in the metal wall of a Faraday cage is going to be a lot more reflective and can easily act like a crude waveguide[1].
