Physics

I’m born from atoms that sing in unison, then march as photons all in line. With mirrors at my ends, I travel straight and fine.

I trap your signal’s wish. Through total reflection I never stray, guiding light both night and day

When light strikes a boundary at just the right steep, it bounces back instead of taking a leap. This keeps your signals in the core confined—name this trick that’s so well-designed. What is it

A single photon comes to call, and down an excited atom it does fall—releasing its twin in perfect sync, doubling light before you blink. What process is this

I trap you between two walls so steep, No matter how you try to leap, Your allowed energies come in steps— No in‐betweens, no missteps.

The more you know about where I hide, The less you learn of how I stride. You can’t pin down both at one glance— Which principle forbids that dance?

I live in space as a complex shape, Square me, and where you’ll find me takes The form of a probability tide— What mysterious wave holds quantum’s guide?

I mark the cut where occupancy ends, At 0 K no one transcends. Call me a “level,” think in joules— I set the rule in metallic schools.
