When you shine a light on an object, the momentum from the
photons that make up that light impacts the object. For macroscopic
objects, this will have no measurable effect. Describe why this is
different for atomic-sized objects.
Suppose you shine a very long wavelength light on one electron
and a very short wavelength light on another electron. What
differences will you observe?
Why does shining very short wavelength photons on an electron
not tell you exactly where the electron...
