Hands In A Bag
A demonstration of infrared vs visible light.
Infrared light can pass right through objects that stop visible light entirely. In the image on the left you can’t see the man’s hands at all - the plastic bag stops the visible light from passing through. Infrared light ‘s also stopped by some things that let visible light through. In infrared light, the eyeglasses are completely opaque.
