A doorway acts as a single slit for light that passes through it, but a doorway is much larger than the wavelength of visible light, so the diffraction angles are very small. Find the angle of the 14th diffraction minimum for a typical doorway if light from a blue laser pointer (? = 473 nm) were used.

1. Estimate the width of the doorway.

2. Find the angle of the 14th diffraction minimum. (Use your estimate
