Consider the slit with width 1.0 cm which has appeared in former pre-class assignments and how

particles with a mass behave in such slits.

a) According to the De Broglie hypothesis, objects with mass can be described as waves. If a

bullet is shot through the slit, how would the wave fronts behave in the slit according to

Huyghens’ principle? Sketch a two-dimensional graph of the wavefronts.

b) If the mass of the bullet is about 20 g and its speed is 200 m/s, how and with which physical

quantities and equations you could assess the probability for the bullet to be diverged essen-

tially from its original direction of propagation?

c) How would the situation change if instead a bullet an electron was flying through the slit?

d) How would the situation change, if in the case of an electron, the width of the slit was just 1.0

Å?
