Yes, the wave and particle properties of light can be observed simultaneously using other experimental setups besides the double-slit experiment. One such example is the "delayed-choice quantum eraser" experiment, which provides a way to observe both wave and particle behavior in a single apparatus.
The delayed-choice quantum eraser experiment builds upon the concept of wave-particle duality and explores the behavior of photons. Here's a simplified description of how it works:
The experiment begins by sending individual photons through a double-slit apparatus. As in the traditional double-slit experiment, the photons exhibit wave-like interference patterns on a screen, suggesting their wave nature.
However, before the photons reach the detection screen, the experiment introduces a device called a "quantum eraser." This device allows the experimenter to choose whether to measure which slit the photon went through (particle behavior) or to erase the information about the slit and preserve the wave-like behavior.
When the quantum eraser is set up to determine which slit the photon passed through, the interference pattern on the detection screen disappears, indicating a particle-like behavior of the photons.
Conversely, when the quantum eraser is set up to erase the information about the slit, the interference pattern reappears, showing the wave-like behavior of the photons.
By selectively using or not using the quantum eraser, the experimenter can observe either particle-like or wave-like behavior, providing simultaneous evidence for the dual nature of light.
It's important to note that the delayed-choice quantum eraser experiment doesn't directly observe both wave and particle properties at the same time for each individual photon. Instead, it demonstrates that the behavior of each photon depends on the experimental setup and the information available to the observer. This experiment highlights the wave-particle duality of light and the role of measurement in determining its behavior.
