Subject: Why does light pass through a lens?
Around 2 a.m.
tomorrow morning, when you want to prove to that traffic cop that you are in
fact not inebriated, explain this to him (or her). Atomically or molecularly,
what is it about glass that lets light pass through it? Do photons pass between
the glass molecules? Does the glass absorb light energy on one surface and emit
it out the opposite surface? What is different between glass and lead that
allows the light through glass and not lead?
If you could answer
this before 2:00 a.m. tomorrow, I would appreciate it.
