Particles pass through a single slit of width 2.3 mm (see Figure 29.15). The de Broglie wavelength of each particle is 612 nm. After the particles pass through the slit, they spread out over a range of angles. Assume that the uncertainty in the position of the particles is one-half the width of the slit, and use the Heisenberg uncertainty principle to determine the minimum range of angles.
