If a photon has enough energy to send an electron to the next energy state, the photon gets absorbed by the electron. If the photon does not have enough energy, does it continue in a straight line? Like does it go through the electron? Or does the electron make sure it stays out of the photons path? Or are such interactions so rare that even though the photon is deflected, it isn't enough for me (at the human level) to notice? Or something else?

Now explain, what is light. is it a photon a particle? or a wave? if is a particle, how does it travel trough infinity to hit your eyes? if it is a wave, then what exactly is waving? through a vacuum of space?

Since glass is almost invisible, I once didn't actually notice the huge glass door infront of me and I banged on the door as I tried to walk through itand got a big cut in my forehead

So what? If it is the matter of amount of space, why must SiO2 be the element? How was the invention of glass? WIsh the video included those

The moment narrator said, But there's a catch. I looked at the title again to make sure this isn't one of the riddle videos.
