- cenamus 1y ago> 10–10^3 photons cm^–2 s^–1 So probably invisible but under the very darkest of conditions?
- ricardobeat 1y agoVisible refers to being in the visible spectrum.
- SkiFire13 1y agoI thought black bodies emitted light the whole spectrum, albeit with differences in the distribution depending on their temperature?
- Sharlin 1y agoYep, but the exponential decay at the short-wavelength end means you're going to hit a single-digit number of photons/m^2/s fairly quickly.
