Doubts this lesson clears up
- Does a mirror count as luminous if it's very shiny and bright?
- Why isn't the Moon luminous if it's so bright in the night sky?
- What about things that glow in the dark after you turn off the light?
- Does something have to be hot to be luminous?
- What if light passes through something—is it luminous?
- Are tube lights and LEDs luminous even though they don't get as hot as a candle?
