This sounds so stupid but I’ve always wondered when you turn off the lights they immediately disappear (I know the light travels fast but where to ?? )
Does each light wave/particle go from its source to disappear continuously?
(The more I write the stupider it sounds sorry)
In: Physics
Every time light hits a surface and bounces off of it, some of that light gets absorbed into it. That’s actually how you can even see things, your eyes are sensitive to absorbing light.
This happens approximately a hundred million times per second in a 3 meter wide room, so even if only 1% gets absorbed in each reflection, it all gets absorbed very quickly.
