I know this is probably a stupid one here.. But like, isn’t light just photons bouncing around? My lightbulb is firing these photons out when it’s switched on but presumably it’s not sucking them back in when it’s off?
So where da light go?
Also shouldn’t it get brighter the longer the light source is on as there’s more photons?
Where are they all going?
In: Physics
they get absorbed. light gets absorbed, thats why you have colours and stuff and everything isn’t just different shades of bright.
since these materials absorb light they gain energy which is why if you shine a light onto something it will become (somewhat) warmer.
a few materials (like glow-in-the-dark-stickers) emit some of that “stored” light over time.
but mostly your light just bounces around a few times and gets absorbed a bit with each bounce.
