Hi I'm reading through a Quantum Mechanics textbook called Quantum Mechanics by Book by Alastair I. M. Rae and in the opening chapter it talks about the Heisenberg uncertainty principle and talks about how a measurement of position of a particle causes an uncertainty from the momentum due to the recoil from the interaction with the illuminating photon.(adsbygoogle = window.adsbygoogle || []).push({});

In the mathematical analysis is sates that in standard optical theory the uncertainty in the resolving uncertainty for the position of an object is.

Δx≈λ/sin(α)

I've tried googling various combinations of the words lens, microscope, resolution, and resolving power and I have not found where this equation/approximation comes from. Can anyone please be of a help?
