SUMMARY
Interference patterns can be generated using a laser beam without splitting it, provided that the setup allows for coherent light to interact. The discussion specifically references using two mirrors separated by 2 cm to reflect light from an incident ray 500 meters away, similar to a Michelson interferometer. Moving one mirror by half a wavelength will indeed alter the interference pattern observed on the screen. Additionally, the coherence length of a typical laser beam is crucial for maintaining the visibility of these patterns.
