Is specific colors are what the object is not reflecting, how are we able to see the white light from a torch mid air?
In: Physics
Sufficiently hot objects produce their own light, a process called “blackbody radiation”
Torches, incandescent bulbs, the sun – they’re not reflecting light from another source, but rather generating light when very hot molecules dump energy to cool off.
The beam of light is reflecting off of tiny particles and imperfections in the air. If you turned on a flash light in a pure vacuum you wouldn’t see the beam at all.
