Heisenberg's Uncertainty Principle states that we cannot simultaneously measure both the position and momentum of an object better than a certain accuracy. This limitation is not a consequence of imperfect technology, but is a fundamental law. It applies to all objects -- photons, electrons, baseballs, etc.
A highly monochromatic, continuous beam of laser light of wavelength 470 nm passes through an electro-optic shutter. The shutter opens and closes in a time interval of Δt = 90 ps
After passing through the shutter to what uncertainty, Δx, have the photons been localized?
