Greetings,(adsbygoogle = window.adsbygoogle || []).push({});

In trying to even ask this question it’s obvious I don’t understand enough about the topic of QM and light.

Here is my attempt at my question:

If I shine a laser beam at a target or sensor – the electronics every time detects the beam. How do the Schrodinger wave equation and the probability calculations and Heisenberg’s uncertainty principle apply to this situation? I assume engineers do not do probability calculations in their circuits.

Does the Schrodinger wave equation and Heisenberg uncertainty principle not apply to a beam of light? (Is it because we are no longer talking about individual photons?)

Bottom line: how do the “main” quantum mechanics equations and principles apply to a beam of laser light?

Curious

Thanks
