It's perhaps worth noting, however, that it wouldn't be unusual for a window to have only ~60% transmittance in visible spectrum.
- mensetmanusman 3y agoA fresh piece of uncoated perfectly clean glass is ~ 90% transparent.
- dghughes 3y agoI think people think that light goes through glass like a laser beam nothing in its way. Just flying right through. But it's actually like a pool ball hitting another pool ago and so on. The original photon of light is not what you see on the other side of the glass.

- liftm 3y agoI did mostly think that. So what's the thing in the glass that gets hit like the "another pool ball"?

- ithkuil 3y agoI found this 3blue1brown video to be a fascinating explaination on how light gets transmitted by transparent material: https://youtu.be/KTzGBJPuJwM?si=hw_SIaklkqfVSGnc https://youtu.be/KTzGBJPuJwM?si=hw_SIaklkqfVSGnc
