I figured out the problem. I approached like a single-slit diffraction problem, and after calculating the wavelength of the bullets, calculated the distance to the "screen" to see half of the spread in the beam. Thanks though. I sort of wish it had been a universe expansion problem!

OP here. So I have tried using Hubble's law, but is this the right approach? Should I be thinking about matter waves?

Homework Statement Bullets of mass 1.53 gm are fired in parallel paths at speeds of 244.4 m/s through a hole 1.99 mm. How far from the hole must you be to detect a 1.77 cm in the beam of bullets Homework Equations The Attempt at a Solution I feel as though some crucial information is missing...

A thin soap film (n=1.318) suspended in air has a uniform thickness. When white light strikes the film at normal incidence, violet light (412 nm) is constructively reflected. At what angle of incidence will green light (564 nm) be most strongly reflected? Assume that the film as the minimum...
