Homework Statement
The diagram is attached. Photons are being beamed with momentum [itex]\rho_{0}[/itex] and mass [itex]m[/itex] at a slit of width A
Estimate the uncertainty [itex]\Delta p_{y}[/itex] emerging from A
Sketch spot size at B as a function of slit width using the uncertainty principle
Determine minimum spot size expected at B as a function of L and the deBroigle wavelegth [itex]\lambda_{0}[/itex]
Homework Equations
[itex]\Delta p_{y}\Delta_{y}=\frac{\hbar}{2}[/itex]
[itex]\lambda=\frac{h}{p}[/itex]
The Attempt at a Solution
My attempt for part one is shown in image two. I achieved an answer of [itex]\frac{h}{\Delta y}[/itex]. [itex]\Delta y[/itex] is represented by [itex]a[/itex] in image one
Part two wants spot size as a function of width of slit - I found it as a function instead of L but I believe the sketch is relatively accurate. I'm not sure how to give it in the form it wants
Part three just throws me for a loop and I really don't have any idea
Thank you as always!
