Yes, the results of the double-slit experiment would be different if two detectors were placed on one side of the slits. In the standard double-slit experiment, when only one detector is used, a wave-like interference pattern is observed on the screen behind the slits. This pattern arises because the particles (e.g., electrons or photons) exhibit wave-like behavior and interfere with each other as they pass through the slits.
However, if two detectors are placed on one side of the slits to measure which slit each particle passes through, the interference pattern is disrupted, and the pattern on the screen becomes a combination of two separate distributions corresponding to the two slits. This phenomenon is known as the "which-way" or "particle-like" behavior.
The act of measuring or determining which path the particles take (via the detectors) collapses the wave function of the particles, causing them to behave more like individual particles rather than waves that can interfere with each other. The presence of the detectors provides information about the path of the particles, destroying the interference pattern that would otherwise be observed.
Therefore, by introducing detectors on one side of the slits, the double-slit experiment transitions from an interference pattern characteristic of wave behavior to a pattern that reflects the individual particle behavior, effectively erasing the wave-like properties of the particles.
