Ex-4.6
The uncertainity in the poisition of electron after it passes through the slit is reduced to width of the slit
delx=a
The uncertainity in momentum = h/a
Position of landing(angle t) = sin t = tan t = delz/dely =(h/a)/2*pi*a= w/2*pi*a
where w=wavelenghth
Rewriting the above expression a*sint = w/(2*pi)
which is similar to a*sint = w (neglect 2*pi)as found out by first minimum in diffraction by a slit of width a
It proves a close connection between wave behaviour and uncertainity principle
