I always knew red light was used when you wanted to keep your eyes adjusted to the night and in old photo development rooms, but never knew the reason why. The shorter wavelength equaling less energy makes so much sense. Also very good video overall. Simple yet effective and easy to understand

How do photons have colors ?
Depends on their wavelength, shorter wavelengths of photons appear blue and longer ones appear red
the colours only exist in our head man
video added to Light n matter playlist. Peace!
The green light cannot draw the hat. So, green is not a creative color?
Radium - the ultimate “glow in the dark”. But also deadly.☢️☠️🧪🟢☢️
